First impression of Tokyo Marui Hi-Capa 5.1 Gold MatchReviewer: Ryan Tacadena
Photo credit to: Anna Tacadena
The newest incarnation of the famed Hi-Capa series to hit the United States. the Gold Match has stunning new accents to make fellow players drool with envy.
As you can see in the two above pictures, the most notable differences between the Gold match and the other pistols in the Hi-Capa line are the Gold plated parts that stand out from the standard black finish.
The gold barrel is a striking contrast to the black slide.
Six deep cuts in the slide also show off the gold barrel and add a beautiful custom look to the slide.
The trigger, hammer, ambidextrous safety, and grip screws are also gold plated to further separate this pistol from the rest of the Hi-Capa line.
Another added feature is the red fiber optic front sight that replaces the standard white dot front sight. Not only does it look cool, it enhances the speed with which you can acquire your target in your sight picture.
The Hi-Capa Gold Match not only lives up to the standard of performance excellence that people have come to expect from Tokyo Marui, it does so in grand style. Come into Echigoya USA and see for yourself what the buzz is about.

Photo credit to: Anna Tacadena
Although it’s been out in Japan for a while, it has only been available in the United States since the beginning of 2015. It is based on the rifle used by Navy S.E.A.L’s.
Based on the 416 D platform but with a shorter barrel designed to be used with a suppressor.
Suppressor attachment on short barrel.
H&K trademark is printed on the bolt shield.
Charging handle has an extended lever. Split D ring for sling mount and ergonomic grip.
Close quarters barrel without suppressor.
Full-length quad rail with long vertical fore grip that has a cut out for a pressure plate.
H&K trademark with rifle designation and caliber.
Rear sight post can be adjusted for height and flips down to make way for optics.
The front sight is adjustable and flips down. The front rail has clips for a sling on both sides and the suppressor has realistic “front towards enemy” markings.
All in all, this is an almost exact replica of the rifle used by the S.E.A.L’s who killed Osama Bin Laden. It’s a beautiful addition to any airsoft collection.

High-speed, low-drag AR-10-style rifle with repeatable sub-MOA precision!
Iron Ridge’s IRA-X family of rifles focuses on getting the important stuff right. The result is a truly exceptional and customizable AR-10-style rifle with all the attention to detail to make it a precision powerhouse. To get the most out of the IRA-X Thor, a Nightforce NXS 5.5-22×56mm scope was mounted.
When it comes to succeeding in a tactical environment, most experts will agree that it ultimately comes down to a matter of doing the basics better. “High-speed, low-drag” doesn’t mean complicated or advanced; it means the ability to perform critical tasks flawlessly under any circumstances—in short, getting the important stuff right. While that wisdom is certainly valid when it comes to tactical skills, it is equally applicable to equipment manufacture. And getting the important stuff right is what Iron Ridge Arms’ IRA-X AR-10-style rifles are all about.
Iron Ridge Arms is a manufacturer and custom shop that specializes in Class II and Class III firearms. Nestled discreetly in an industrial park in Longmont, Colorado, it is owned and operated by veteran gunsmith, machinist and designer Oliver Mazurkiewicz. Through his many years of experience customizing and modifying all brands of tactical rifles and carbines, Mazurkiewicz developed a keen understanding of the critical qualities necessary in that breed. And while many manufacturers do an excellent job of providing these qualities, as a custom gunsmith, Mazurkiewicz always saw room for improvement. He believed that if that extra attention to detail were incorporated into the fundamental construction of the rifle, its “basics” would literally be as good as they could get.
Starting with the right foundation—the IRA-X has meticulously machined upper and lower receivers that are fitted perfectly to withstand the harshest conditions.
The core of the IRA-X is its meticulously machined upper and lower receiver. Designed and engineered to meet Mazurkiewicz’s exacting specifications, these parts are CNC-machined from solid billets of 7075-T6 aluminum in the Iron Ridge shop. Although they are designed to accept components purchased from DPMS, which Mazurkiewicz has carefully selected as “the standard” of quality and consistency for drop-in parts, they are not your run-of-the-mill receivers.
The IRA-X Thor tested for this article featured a custom-machined Rock Creek barrel fitted with a SureFire FH762K03 flash suppressor.

American Fork, UT S.W.A.T. transitions to Ruger’s new SR-556 rifle!
The S.W.A.T. environment is a 360-degree world, and the fast-handling Ruger SR-556 was up to the challenge of being deployed from all angles and distances.
While it is certainly true that smaller departments do not face all of the problems a big agency experiences, the idea that “all cops are the same” and “policing is the same everywhere” strikes me mostly as political rhetoric. Parts of the day-to-day job may be similar, but working as a police officer in a 15-man department is not the “same” as a 35,000 man department. Each faces their own set of challenges, some similar, many completely different.
One of the challenges faced by many smaller police departments, is dealing with big-city crime with small-city assets. Two of the areas where this has very significant impact are training and tactical deployments. Large departments often have training divisions as contrasted to a smaller agency that likely does not even have training officers. That is something an officer does in conjunction with the rest of their duties. The same is true for S.W.A.T. teams. Watching the various television shows you would think everyone has a dedicated S.W.A.T. team with vans, ‘copters and tanks. That is simply not true. Most do their job and train for it when they are not “on duty.”
The Ruger is well equipped from the factory. Simply add a sling and optic of your choice and you are ready for the next callout.

https://echigoyaworks.militaryblog.jp/e348231.htmlSun, 29 Jul 2012 16:00:00 +0900Sig Sauer 1911 Scorpion私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。
Sig Sauer has a reputation for making high quality and innovative firearms. A few weeks ago we took a look at the S&W 329PD as a backup handgun when carrying afield. Given that 2011 is the centennial of Jonathan Browning's excellent 1911 pistol; we decided to take a look at Sig Sauer's new 1911 Scorpion. While the 1911 in 45ACP doesn't pack the punch of some revolver only cartridges, its durability and reliability has made it a favorite of hunters for generations.
The Sig Sauer 1911 Scorpion.
Sig is not new to manufacturing 1911's, having produced many models under the GSR label for years. They also produced the Sig 220 in a variety of cartridges (although 45ACP is the only production cartridge today) for decades. The 220 in a SA/DA configuration is definitely different than a 1911, but the slim profile and similar ergonomics to the 1911 make it a good choice when considering a single stack, all metal, 45ACP pistol.
The most noticeable features of the new 1911 Scorpion is the new Hogue G10 grips and the desert tan Cerakote finish. The grips, with what Hogue calls "Piranha" texturing, really grabs the hands. Combine the grip with the high lines-per-inch front strap checking and the Scorpion does not lack in hand grip, which makes the gun easier to control under slick wet conditions. In addition the grip also has an integrated back strap and beveled out magazine well extension that make it easier to guide in a loaded magazine when reloading.
The Hogue G10 Piranha grip is colorful and adds a good deal of texture. A nice addition in the back strap has been changed out for the matching texturing as well.
The grip and back strap come together to form an extended magazine well that helps guide in a quick magazine reload.
The other noticeable feature is the factory Cerakote finish that has been applied over the stainless steel frame and slide. Cerakote is a ceramic based finish that armors the firearm and improves abrasion and corrosion resistance. This makes the Scorpion much more resistant to scratches and rust. While we did not test the coating for scratch resistance, past experience with other firearms coated with Cerakote or Duracoat have proven to be effective in fighting scratches and rust. Although you should always still take the time to clean off your guns after use and/or after getting wet.
Two piece feed ramp. Notice also that the Cerakote finish is on the inside of the slide as well as the frame.
Beyond the grips and finish, Sig has included a variety of other features that have come to be expected of a higher end 1911. Namely low profile tritium night sights, a lightweight trigger, a larger external extractor, beaver-tail safety grip, and an ambidextrous safety. The ambidextrous safety uses the "short" format which is nice if you intend to equip the Scorpion with a Crimson Trace laser grip. Longer, standard ambidextrous safeties tend to hit the laser housing and do not work correctly. The Scorpion is also equipped with a picatinny front rail for attaching lights or lasers at your discretion. Sig also includes two eight round magazines with the Scorpion.
The "short" ambidextrous safety. The Scorpion also includes low profile Trijicon night sights.
The Scorpion does not have a full length guide rod, but it does include a picatinny rail.
The Scorpion, like most Sig 1911's, is exceptionally tight out of the box. There is little wobble in the slide and will take a few hundred rounds to break in. The trigger breaks cleanly and crisply with no noticeable burrs.
On the downsides the Scorpion does not have a full length guide rod, no front slide serrations, and the barrel ramp is a standard two piece design. We are also not particularly fond of the flat triggers; however this is personal preference and being a 1911 the trigger can be changed.
Overall the Scorpion is an excellent offering considering the asking price. It should be long lasting and corrosion/scratch resistant and offers an excellent grip. The 1911 makes an excellent back up firearm when in the backcountry and the Scorpion is worth considering if you're in the market for a new sidearm.

Custom-quality 1911 at a duty-ready price point!
The X-TAC from Wilson Combat is a simple and straightforward custom 1911, featuring highly effective “X” pattern serrations adorning the slide and the grip frame of the pistol.
THE 1911 PISTOL has experienced a pretty significant resurgence in the last few years. A pistol that was once maligned as “too aggressive” or “unsafe” by police administrators is once again gaining wider acceptance. With the exception of a few states, and some less knowledgeable administrators and armorers this mythology has all but disappeared. Agencies are not only allowing the 1911 pistol as a personal choice, many are moving to them department wide. It is a testament to the design for sure. The 1911 pistol is rugged, reliable, accurate and has proven itself in actual gunfights time and time again. Tactical teams and high-risk units have used them for years with great success. Given the opportunity, many special operations units will take a 1911 over just about any other pistol. It is a proven design, and as is often the case, it is making a full circle back into popularity.
There is a reason this particular design has withstood the times — it aims and shoots naturally for most people almost without regard to experience level. Given various grip changes it can accommodate most any hand, and the slim design makes it perfect for inside the waistband carry. Given the quality of materials and machining today they can be built to incredible tolerances. Even some custom pistols today cost less than the same upgrades would have cost 15 years ago. It has really put the 1911 in a place where it can accommodate just about any task it is called upon to undertake.
The X-TAC features a non-ambidextrous thumb safety as well a generously upswept beavertail grip safety to help prevent “hammer bite.”
During the initial onslaught of the polymer pistol, the 1911 enjoyed broad use in the police world, especially undercover, off-duty, or in plainclothes. This was especially true for agencies that issued 5-shot .38 Special revolvers to their detectives. Many wanted the extra capacity and the ability to use the venerable .45 ACP cartridge. This was especially true for those officers that found themselves in need of their pistol as something other than a desk ornament.
Key to the X-TAC’s excellent handling characteristics is the “X” pattern serrations on the front- and backstraps. The X-TAC features Wilson Combat’s iconic “Starburst” grips, featuring smooth grooves radiating out from the center.

Seven short-barrel rifle uppers to fit an array of mission requirements!
SBRs (Short-Barreled Rifles) offer a lot of practicality in a small package, for a price that is significantly less than the select-fire rifle or sub gun. Manufacturers such as CMMG, LaRue Tactical, LWRC International, Stag Arms, Troy Industries, Wilson Combat and Noveske Rifle Works (above represent a wide range of products and price points to meet the specific needs of the end-user.
The 12″ LaRue Stealth can serve in both a CQB and precision rifle role. It is shown here equipped with a Magpul PRS stock, Leupold MK 4 scope with LaRue mount, and SureFire’s new Mini suppressor.
The CMMG 7″ upper is among the shortest of the short-barrels, shown here with an Aimpoint Comp M4S, S&W/Troy Back-up Iron Sights and a Magpul Angled Foregrip.
The 8″ LWRC PSD is a piston rifle that is designed for CQB and protective missions. It is equipped with Magpul MOE stock and grip, an Aimpoint T-1 Micro with a LaRue mount and LWRC iron sights shown in the raised position.
The Noveske Rifeworks upper is based on a VLTOR upper receiver and features a 10.5″ polygonal-rifled barrel, Noveske rail, and the Switchblock. It is also shown with the Aimpoint T-1 and SureFire Mini suppressor.
Troy Industries offers the M7 conversion as a kit. Note the Troy vertical grip, pistol grip and sights. The Aimpoint T-1 is mounted on the shorter LaRue mount for an absolute co-index. The complete rifle can be broken down and transported in the factory-provided Hardigg case.
Stag Arms can provide their rifles and uppers in both right- and left-hand versions. The 11.5″ upper features a Samson rail, standard front sight, Arms 71L-R rear sight, and an A2 flash suppressor.
The Wilson Combat upper features a match-grade barrel and their new TRIM rail. It is a slim-line rail that allows the user to mount short Picatinny rail sections in the desired location.

The Ruger 10/22 is the premier semi-automatic, rimfire rifle in the world today. Introduced almost 50 years ago, Ruger has sold millions of the ultra-reliable 10/22 rifles since 1964.
The 10/22 fires the affordable .22 LR cartridge, meaning a shooter can spend hours of great fun at the range without breaking the bank. Ruger’s rotary magazine is extremely reliable, and a 10 round magazine is standard with all new guns. Ruger also makes a five round magazine, and introduced a factory 25 round magazine in May of 2011.
In addition to its rugged reliability, firearm enthusiasts love the 10/22 for its versatility. Ruger makes the rifle in a variety of configurations with synthetic and wood stocks, varying barrel lengths and finishes. In years past, Ruger chambered the 10/22 in both the .22 WMR and .17 HMR cartridges.
The Ruger 10/22 rifle exhibits great handling characteristics, and unlike many .22 LR rifles, it is designed for an adult. This means the gun has excellent fit characteristics for many people. Prior to 1964, many .22 LR rifles were smaller, youth-type guns.
The receiver is precision machined from aluminum alloy, though the now discontinued .22 WMR model used a steel receiver. The 10/22 is a straight blowback design, which has proved to be exceptionally reliable in this rifle.
Airsoft version of the Ruger 10/22 is the KJworks Hawkeye

Underground Skunkworks’ rugged, surgical sniper with a 3/8-MOA guarantee!
Hand finished from muzzle to receiver, the Perseus features an 11-degree recessed crown. Its threads are cut to within .0001-inch or less. With its adjustable Manners MCS-T4A stock, the precise and solidly built Perseus provides the shooter with an instantly stable and consistent firing platform.
In an age where new offerings come with equal parts marketing pitch and reductive disclaimers, it is a bit of a shock, at first, to encounter a rifle that not only shoots to its manufacturer’s claims, but exceeds them. The Columbia Falls, Montana, rifle company Underground Skunkworks, or UGSW for short, has produced what might be the finest production precision rifle on the market today—the Perseus. Designed for law enforcement missions requiring surgical engagements of targets, the Perseus is a rugged and reliable tool with razor-thin accuracy.
Sporting a custom-designed, Timney-made trigger, the Perseus’ 911 action can accept AW or AICS magazines and be topped off via the breech.
From his humble beginnings as an engineer, UGSW President and Founder Mike Bush has applied an obsessive attention to detail and practical design techniques to correct the flaws and enhance the strengths of the modern-era bolt-action precision rifle. Raised at his father’s elbow, who was a law enforcement officer, in their Mobile, Alabama, diesel shop, Bush went on to earn a degree in electronics engineering. With both a formal and practical education in engineering and design, Bush fostered a lifelong interest in perfecting mechanical precision and long-range shooting. Watching firsthand as FBI HRT shooters tested, broke, fixed and improved upon existing production rifles, Bush learned a crucial lesson in rifle design: “I was disappointed in what I saw as an across-the-board inconsistency in the tolerances of production rifles. Twist rates, fit and finish varied considerably within a single model produced in the same production run from the same factory.”
For the Perseus, Bush set out to design a duty rifle that modernized the M24/M40 platform, keeping what worked and eliminating what did not. “The core capability of this system had to provide both cold-bore and sustained-fire accuracy. There is little on the rifle that is not available somewhere on the open market, but the key is how the highest quality components are harmonized and fit.”
The Perseus features oversized bolt knobs and an Oberndorf-style mag release for fast handling in wet conditions or with gloved hands.

Swiss twist on a classic design with features that today’s SWAT officers demand!
Sig Sauer’s 1911 Tactical Operations pistol is as reliable as it is versatile, shown here with a SureFire X400.
The most enduring design of John Browning remains the 1911 pistol. In fact, a good argument can be made that the 1911 is the most timeless handgun of all time. Taking that position one step further, you would be very hard-pressed to come up with another technological innovation introduced 100 years ago that remains on the cutting edge today. For the better part of the 20th century, commercially made 1911s were only available from a single source. That has all changed and 1911 pistols are now available from a number of manufacturers. However, quality varies tremendously and in the end you’ll get exactly what you paid for.
A few years ago, Sig Sauer introduced a line of 1911 pistols, a move that took many of us by surprise. After all, Sig Sauer was turning out some first rate DA pistols. Why make a move into unknown territory? Why not? If this firm could turn out a world class DA pistol, they just might be able to apply that expertise to the most popular self-loading pistol of all time.
Ambi safety is standard on the Sig Tactical Operations pistol.
Recently, I was able to check out a Sig Sauer 1911 Tactical Operations pistol chambered in .45 ACP. The Tactical Operations pistol is a full-size, all-steel 1911 pistol that has everything you need and nothing you don’t. As its name implies, this heavy-duty pistol is designed for the SWAT officer, but would also be a solid choice for patrol or personal defense.
Like all Sig Sauer 1911 pistols, the Tactical Operations embodies the classic qualities of the Browning original along with modern innovation.

Built and bred for battle—high-end match-grade combat rifle!
With a reputation like JP Enterprises’, the PSC-11 lives up to its predecessors’ ability for first-shot accuracy, and it definitely has the ability to pile bullets into tight groups when it runs hot, too.
When I first held JP Enterprises’ new PSC-11 rifle in my hands last year, my first thought was that somebody left one of their JPE CTR-02s and an LRP-07 in a dark corner of the shop, put on some mood music and let nature take its course. In reality, John Paul, the owner of JP Enterprises, listened to requests from shooters who wanted a high-quality, accurate AR upper to fit their lower receivers. It wasn’t too much of a stretch to take the best features of the LRP-07 and blend them with a CTR-02 to create the new rifle.
This JPE PSC-11 is tricked out with a 4.5-14x Leupold Mark 4, Accu-Shot’s high-grade monopod, Atlas bipod, and Magpul’s PRS buttstock, adjustable grip and magazine. The rifle’s .223 Wylde chambering lies between the .223 and 5.56mm NATO dimensions, boosting versatility.
“With the introduction of our new SCR-11 platform, we knew serious shooters would want to incorporate the JP side-charge system into their existing small-frame gas gun,” John Paul said. “That’s why we are introduced the new PSC-11 in 2011. This upper combines all the great features and performance of the new SCR-11 in a package that is cross-compatible with any standard lower receiver on the market. This new upper system is designed for the all-out tactical market with redundant side and top charging systems, dust cover, forward assist and an optional key-slot gas plug for those running suppressed systems.”
Shoulder-mounted charging is quick and easy with JPE’s side-charge system, but if you’re a traditionalist, it still has a standard AR charging handle.

Precision performance for the LE Designated Marksman with devastating punch!
Remington 40-XS in .338 Lapua bridges the gap between .308 and .50 BMG in a state of the art bolt action rifle that delivers the goods in terms of both accuracy and terminal ballistics.
THE .338 Lapua Mag is a precision tactical cartridge whose time has come. Originally developed in 1983 at the request of the U.S. Navy, the .338 uses a necked down .416 Rigby case and in its initial configuration launched a 250-grain bullet at nearly 3,000 feet per second (fps) with a muzzle energy of over 4,800 foot pounds of energy (fpe). Research Armament produced a prototype rifle and ammunition that were tested by the Navy, but the cartridge never was put into production in the United States. Lapua and Norma finished development of the .338 and began manufacturing the cartridge under the Lapua name. Besides Lapua, Black Hills also loads both 250- and 300-grain cartridges. The latter bullet leaves the muzzle at 2,800 fps with a prodigious 5,223 fpe. To put this into perspective, a 168-grain .308 match cartridge has a muzzle velocity of only about 2,600 fps and 2,180 fpe. The .308’s ballistics pale in comparison to the .338 Lapua, although most .338 rifles are only marginally heavier than precision tactical rifles chambered for the .308.
When raised up, the McMillan A5’s adjustable cheekpiece is designed not to conflict with the “bolt throw” of the host rifle.
The Remington Model 40-XS, for example, is only slightly larger and heavier than similar rifles in smaller calibers, weighing in at 16 pounds — complete with scope and bipod. The test rifle uses Remington’s Model 40-XS action in a McMillan A5 stock. Naturally, a large cartridge like the .338 will necessarily deliver more felt recoil than lesser cartridges, but this can be offset by the use of muzzle brakes. The Remington muzzle brake reduces felt recoil to approximately that of a .308, although muzzle blast alongside the rifle is significant. The spotter on a precision tactical team using a Remington 40-XS .338 Lapua Mag should position himself slightly to the rear of the shooter’s shoulder to avoid having gases and dust blown into his face. As the .338 Lapua Mag became accepted by a number of the world’s military forces as replacements for, or supplements to bridge the gap between the .308 and .50 BMG, it was only a matter of time before law enforcement began to consider it. The .338 gives the precision tactical marksman a huge range advantage over any .308 caliber rifle, while adding little to the weight burden that every rifleman must contend with. As mentioned, the test rifle weighs only 16 pounds (fully loaded) and I’ve tested .308 caliber precision tactical rifles that weigh about the same. When compared to .50 BMG caliber rifles, the Remington 40-XS weighs nearly 10 pounds less than the lightest weight .50 BMG rifle I’ve ever tested. Most .50 BMG rifles, like the widely used Barrett M82, weigh over 30 pounds.
The aggressively designed muzzle brake of the 40-XS helped tame the recoil of the .338 Lapua Mag chambering down to manageable .308 levels.

Germany’s armed forces adopt HK’s new 5.56mm MG4 lightweight squad auto!
German gun maker Heckler & Koch (HK) is well known for breaking molds. The engineers in Oberndorf are not afraid to blaze new trails with guns like the G36 assault rifle with its polymer construction and integral optics. Note I said “optics,” plural: The G36A1 sports both a red-dot sight and a 4X scope stacked on top each other in a sort of figure 8.
When it came time to upgrade the army’s squad machinegun, the Bundeswehr naturally turned to HK to develop a weapon. Yes, the Germans could have bought M249 SAWs from FN in neighboring Belgium, but that’s not how they operate in Europe’s foremost manufacturing country. The Bundeswehr wanted a German gun. I can’t blame them at all. In a quick digression, I note with alarm that America’s military cares not a whit about sustaining our own domestic small-arms development capability.
We bought Beretta pistols from Italy. We awarded FN the contract to develop the SCAR. Glock pistols were recently bought by the hundreds of thousands to give to Iraqi cops. I would like to see our military try a little “buy at home” for a change, like the Germans do.
And so HK was tasked with developing a SAW-like weapon: a belt-fed 5.56mm light machinegun that can be adapted for an assault mode as well as a fixed position mode (i.e., tripod mounted). The result was the MG43 which first appeared in 2001 and was later type-classified and adopted by the Budeswehr as the MG4. By 2007, the MG4 had replaced the previous MG3, a 7.62mm machinegun, on vehicles and for ground troops.
The MG4 is a definite departure for HK as it’s a conventional gas-operated, rotary cam design whereas previous German machineguns have relied on the distinctive Vorgrimler-designed roller-delayed blowback action.

Extremely high-precision downrange dominator with sniper rifle accuracy!
This U.S. Marine loved the D&L PPC and the SureFire 60-round mag shown here. He will soon deploy and wishes he could take both with him.
Quite alive and well, the old slogan “buyer beware” pertains to, well, everything we buy. A life-long, daily risk management drill, you ask? You bet, and firearms are certainly no exception. Take the AR-15 platform, but don’t try to count all the clones or you may hurt your eyes, as they can run the gamut of the good, bad and the ugly. Did you hear about the small quantity of aftermarket ARs last year that were equipped with bolts made in Turkey? Except for the bolts, the guns were fine. Sure, you can cut corners, but not at the corner of “bolt and carrier.” When you do, a big accident is waiting to happen.
Using four mounting bolts, D&L’s receiver scope base is extremely secure, as is its eight-bolt handguard and 60-screw 30mm scope rings.
Case in point, an accident occurred while in the hands of a police officer who was the (short-lived) proud owner of the new AR clone. Fortunately, God was at the range when all six lugs sheered off, allowing the bolt to blow rearward without rotating. The upper receiver was destroyed and all other upper parts, except the barrel, were ready for a dirt nap. The lower suffered no damage and, most importantly, the police officer suffered only a face speckled by tiny aluminum shards, with his glasses saving his eyes. Yes, you can get what you pay for, but sometimes it’s worth less than the asking price.
Even without its winter plumage, D&L’s Professional Perimeter Carbine would stand out in a crowd. Many of its features are unique to D&L Sports, including its aluminum stock, free-floating, ventilated handguard, and muzzle brake/flash suppressor. The scope tested with the rifle was a Leupold 3-9×42mm.
When compared with some, the AR-15-type rifle is a highly technical rifle; not only in design, but also in the mil-spec requirements assuring that it is made of the finest materials to the highest quality control. It isn’t rocket science, but it is vital to the operation and safety of rifle and operator.
Built to endure harsh usage, D&L’s aluminum AR buttstock comes with two waterproof storage tubes. They also make an adjustable length-of-pull version.

Fighting 1911 that overcame rigorous testing to become the FBI’s “go-to” tactical pistol!
Every feature of the Professional Model was specified in the RFP by the Bureau, and each submission for the original FBI contract was required to meet demanding endurance and accuracy requirements.
When the FBI adopted the Springfield Professional 1911 in 1998, new respect was bestowed on the old workhorse. The Professional is the result of a Request for Proposal (RFP) that was issued in 1995 in an effort to standardize the pistol for all of their regional SWAT operators. The RFP was extremely demanding and considered by some to be unreasonable. While half a dozen or so manufacturers and shops submitted guns, there would only be one winner. One of those vying for a chance at the contract was Dave Williams, Springfield’s Custom Shop Director.
Origins
At first glance, the Professional may not seem all that unique or different but, in 1998, it set the world on fire. After all, the country’s “premier law enforcement agency” had chosen a design that was some 90 years old. For those who are not familiar with this pistol, the Professional Model is a single-stack 1911 pistol that is built entirely in Springfield’s Custom Shop. The slide and frame start as semi-finished parts and the shop’s staff cut the rails, drill the pin holes and hand fit every part.
The Bureau specified Novak low-mount tritium sights, an extended ambidextrous safety, beavertail grip safety, magazine well, 20-lines-per-inch checkered frontstrap, and match-grade internal components. The proposal also called for Walter Birdsong’s Black- T finish and required the pistols to be shipped with five Wilson 47D 8-round magazines. On top of all this, the manufacturer was required to warranty the pistol for an astounding 50,000 rounds.

Designed by operators for operators with all the features that patrol officers need!
The Sionics SAR-15-QR10 offers true no-nonsense Mil-Spec quality at the right price for today’s law enforcement needs. It is shown equipped with an EOTech 553.A65TAN HWS and Atlas Precision BT10 bipod.
Sionics Weapon Systems is a fairly new AR rifle manufacturer that is committed to delivering the highest quality Mil-Spec no-nonsense guns at the lowest possible price. And judging by its SAR-15-QR10 rifle, I would say they have succeeded.
Sionics SAR-15-QR10 exhibited tight tolerances between the upper and lower receivers and an excellent finish.
The staff and management at Sionics is made up of former military and law enforcement personnel who know what it means to depend on your weapon system. Josh Ellis, the owner of Sionics, has worked closely with many police armorers to ensure that his rifle meets their needs. It has been extensively tested and approved by the Tucson Police Department as a patrol rifle. According to Ellis, Sionics rifles are being used by federal agents as well as being currently evaluated by several law enforcement agencies.
The SAR-15-QR10 sports an olive drab Magpul ACS carbine stock, MIAD pistol grip, MOE enlarged triggerguard, XTM rail panels, PMag and MBUS flip-up front and rear sights.
The SAR-15 is a direct gas impingement 5.56mm NATO semi-auto rifle exhibiting above standard quality. The fit and finish and attention to detail are equivalent to what one would expect from a custom gun shop and with some extras as well.

Wilson Combat’s SBR Tactical is extremely powerful yet easy to maneuver with in close quarters. Wilson’s proprietary 7.62×40 WT cartridge has just the right amount of knockdown power to pair with the SBR’s barrel. This is truly a versatile platform. Shown here with an Aimpoint CompM3.
New chamberings come and go all the time, and this has always been the nature of the business. Someone is always trying to improve on existing cartridges, platforms and systems. It is this innovation that makes the firearms industry as strong as it is.
One of the longest standing of these projects has been the short .30 caliber for the AR platform. Since the first time a U.S. soldier fought against the AK-47 and its 7.62×39mm cartridge, the industry has tried to make that round (or one like it) work in an AR. It is a project that continues to this day, resulting in cartridges like the 300 AAC Blackout, .300 Whisper and a few others. They are all an attempt to approximate the ballistics of the 7.62×39mm and function properly in an AR-type rifle. For most, that is as close to 2,400 feet per second (fps) as you can get with a 125-grain bullet. New powders, bullets and precise manufacturing have made this better with each passing year. But getting these cartridges to fire has never really been the issue—it has been getting them to work in magazines.
The Wilson Combat Whisper762 suppressor does little to affect the balance of the SBR Tactical—it’s lightweight, quiet, and reliable. During range tests, the suppressor showed no signs of shifting the point of impact. It provided minimal backpressure, never came loose, and maintained excellent sound suppression.
Take a close look at an AK-47 magazine. It curves almost immediately. Other than the lip of the magazine, about an inch or so, it is one continuous curve. This is necessary for the ammunition to feed properly past about ten rounds, given the cartridge diameter. You could make a straight magazine, of course, but it would be too long to be practical, and still presents its own set of issues. You need the curve in order to make it practical with a 30-round magazine—even for a 20- or 25-rounder. Without this curve, the rounds will bunch up in the middle and cause malfunctions. It is just one of those laws of physics that cannot be circumvented.
Wilson builds their SBR with their TTU (Tactical Trigger Unit), which provides operators with a clean two-stage trigger.
