Wilson Combat SBR Tactical 7.62×40 WT
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。
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.

Sionics Weapon Systems SAR -15-QR10
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。
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.

VSR10 Gspec
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。
This my Tokyo Marui Gspec. This is full stock and shooting at 89m/s. I will show a step by step takedown and will also show you how to make it shoot at 96-98m/s just by changing the inner brass barrel with the PSS10 430 mm 6.03 barrel.
I will be installing the following:
PDI light bull barrel
PDI bull barrel cap
PDI barrel space
PSS10 6.03 tightbore barrel 430mm
First remove the dummy silencer (you dont have have to if you ample space). Then remove these two screws near the magazine well. after removing screws you can pull the upper assembly out in upward motion.
This is the mag catch assembly, be careful because they have a tendency to fly off and they are hard to find.
Showing the upper separated from the lower.
Now remove this screw.
And loosen these two screws, no need to remove. You just need to loosen them so you can unscrew the barrel from the barrel base.
After separating the barrel from the barrel base, you are now ready to remove the inner barrel assembly. First remove these two screws.
Also take out this screw to remove the hop-up lever.
Now we are ready to replace the TM brass barrel with the PSS10 barrel
First remove the 3 screws that holds the barrel (in green) and then the two screws (in red) to open the hop assembly
All disassembled as shown here. Just replace the barrel and reassemble it back.
Now to prepare the bull barrel, first we need to insert the barrel spacer inside the bull space. They are a little bit tight but I rubbed a few drops of silicon into the o-rings.
Then using the brass barrel I removed to push it into place
Now you are ready to insert the inner barrel assembly
Push it into place and make sure these two holes are aligned. It is where one of the screw goes. After aligning, you also need the put back the hopup lever.
As shown here you are ready to screw on the barrel into the barrel base
I suggest using a little bit of teflon tape
You can also remove the hop sticker into the new one
And install the bull barrel cap anywhere during the process
And from here it is just reverse reassembly and you have new look. In installing the 430mm PSS10 tightbore barrel you gain at least 7-9m/s. I already upgraded 3 gspec with just that barrel and it is always the case. I havent tried the pdi since I am already getting good results with the laylax PSS10.
Photos of the final look of my VSR will be posted after I out the finishing touches. I am planning to paint it and I will also post the process here so keep posted.

Springfield .45 Professional
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。
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.
