I go back today to write about the maxillofacial protection systems since we have been mentioning these in our previous feature stories. This time, I go over the different products that MTEK Weapons Systems developed. Called the Predator Facial Armor System, these come in three different configurations and these cover different tactical situations. Dr. Airsoft of Airsoft Medicine highly approves the protective features of the Predator Facial Armor System, though he readily points out some flaws in these such as hearing yourself loud or the inability to hear background noise to detect the OPFOR approaching.

Even with these flaws, the protective features of the Predator Facial Armor System would trump the flaws, especially in airsoft where safety is more paramount than actual tactical concerns. While there are no replicas of these for the airsoft market, these are affordable enough, and money is usually no object when spending on protective gear.

MTEK PREDATOR FAST G3A



Design for convoy operations. This model can also be used for checkpoint duties and room clearing/CQB operations. This model meets higher impact ballistic protection it is designe for close quarters. This cpme with the MWS Clear Blast Visor, 100D Cordura Cover, ACC Rail, and Team Wendy Zap pads.

MTEK PREDATOR FAST G3C



The problem with facial protective gear, especially at the mandible area, is that using the cheek piece of rifles would become is not very feasible, and thus, aiming properly does not happen with users resorting to special scope mounts to adjust their optics/sighting equipment at a higher or even unsual configurations to zeroin their rifles. Also, the bulk of the mandible protection raises the head, which means the shooter's profile is further exposed. The FAST G36C was designed for using cheek piece and it flexes allowing the operator to further press his/her face to the stock's cheek piece, lowering the shooting profile and achieving proper aiming just like without wearing a mandible protection. This comes with an ACC rail to mount to the helmet.

MTEK PREDATOR FAST T3C



Since both the FAST G3A and G3C aimed are restricted to those with Federal or State IDs and also more expensive (the G3A is US$649 while the G3C is US$419), the T3C is aimed for the training and milsim market, which airsoft is covered, but without the ballistic protection that its more expensive siblings provide. The protection provided by the FAST T3C is already more than adequate to use for airsoft and at US$89.00 (on sale right now at US$60), it is not a restricted item and thus, easy to purchase. It works the same as the FAST G3C, sans the ballistic protection. This is the product that Dr. Airsoft reviewed and highly recommends.




ACCESSORIES

There are various accessories to use the Predator Facial Armor System. Starting with the Versa Mount, this allows you to mount the G-Series to various helmet types such as the ACH, LWC, TC-2XXX, etc. The ACC rail is a rail mount system that can be accommodated by the Versa Mount so you can attach some accessories such as helmet cams and rail-mounted tactical lighting. The MWS Blast Visor is designed more for the G3A to provide a complete facial armor protection system. With the G3C and T3C, you can use other ballistic goggles and glasses.

The M&P 15-22P has a 6" barrel and a magazine capacity of 25 rounds. It can be described as cute but this weapon is definitely lethal.




It is similar to the airsoft version made by G&Ps Combat Monster.

The M4-SD Tactical Compensator from Griffin Armament is a black-oxide, stainless steel military-style muzzle device offering low concussion, flash and excellent muzzle control, as well as compatibility with a number of sound suppressors.

There has been a market for muzzle devices as far as I can remember - flash hiders, brakes, compensators etc. The standard A2 compensator is still the most economical choice, but there are always folk looking for improved performance over the standard. Flash hiders reduce flash signature while compensators or brakes either aim to reduce felt recoil or muzzle jump/movement. The idea is to keep the muzzle as neutral as possible when shooting, so that any movement seen by the shooter is due to his own input. Less movement means quicker follow-up shots, or less need to adjust one's position after firing a shot. Granted, the 5.56mm round doesn't have much recoil to begin with, but if you could make it shoot like a .22 LR, why not? For the most part, muzzle brakes do a decent job of reducing muzzle movement but at the expense of increased side blast, flash and concussion. Then there are muzzle devices that attempt to strike a balance between all the desired attributes, like the PWS FSC556 and Battlecomp.

A new entry into this market is the M4-SD tactical compensator, from Griffin Armament.






Description - The M4-SD is a military-style muzzle device, designed to reduce muzzle rise and offer recoil control, while keeping concussion and flash levels to a manageable level. The M4-SD is named after Griffin's M4-SD sound suppressor, and it's compatible with the Gemtech HALO, SRT Typhoon with Atlas mount, Quicksilver's QD223, Coastal's FDX-FHM and the AAC Omni (basically, any A2-compatible suppressor mount). It's made out of 17-4PH stainless steel, and finished in black oxide.

The M4-SD is the same 22mm (.865") diameter as the standard A2 compensator, and is 1.75" long. The main portion of the comp has a slightly reduced diameter, and has 11 rows of 5 ports/holes drilled into it. The 55 holes are .078" in diameter and have .025" chamfers. At the front are 6 holes, of the same size. The concept is similar to the KAC Triple Tap and Battlecomp, but using holes instead of slots. The comp is closed on the bottom.

The M4-SD was designed to be optimized for use with sound suppressors, and is constructed with thick walls to prevent expansion of the comp inside a suppressor under use, where it's exposed to a very harsh thermal environment. Strength is the reason why the ports are configured in rings, rather than staggering or offsetting them.

The M4-SD can be installed with a crush washer to achieve the correct clocking so that the closed section is on the bottom, but peel washers are recommended for use with some suppressor mounts. I mounted the M4-SD on my Addax Tactical ATAC GPU, which is one of my favourite uppers to shoot. It's a very soft-shooting piston upper, and feels no worse than a DI gun, unlike most other piston guns I've shot.

Falcon Industries’ ERGO Z Float Rail series has a unique 2-piece design that it can be installed without taking the barrel off. This handguard is great for those AR owners that don’t own any gunsmith tool and those that have an AR with permanently attached muzzle device.



To install the ERGO Z Float Rail, the Delta ring assembly needs to be removed. The simple way to do so is by cutting the ring and spring off carefully with a small rotary cutter or a hacksaw. I recommend wrapping the surrounding areas with duct taps to protect them from any slip of the cutter. Of course, if you have the proper gunsmith tools to take apart the barrel assembly, the Z Rail can be install like any typical free float handguard.



The ERGO handguard mounts on to the stock barrel nut and uses six long bolts to lock it in place. The two halves are lock together by two short tapped screws in the front and two in the back. There are cut grooves on rear of both the handguard pieces that fit on the stock barrel nut’s teeth for the proper alignment.

The new 10” extended carbine-length Z Rail M-4 “Over Shoot” model features an open-top front section to fit the A2 front sight or a rail gas block. The standard 7” model mounts flush against the front sight base. The ERGO Z Float Rail is compatible with Adams Arms and most other AR gas piston systems.

Steve Hine from Falcon Industries had informed me that they are releasing updated versions of the Z Rail handguard. The new versions have additional lightening cuts on the inner surfaces. The locking mechanism had also been simplified by eliminating the steel locking plates. The six side locking bolts are now using threaded inserts that are built into the two halve pieces. The total weight will be few ounces lighter on the new versions.






**Size**: 7-inch carbine length and 10-inch Extended Carbine Length
**Type**: Quad-rail, 2-piece design
**Weight**: 13.2 oz and 15 oz
**Construction**: CNC aircraft-grade aluminum
**Inside Diameter**: 1.15”
**Continuous Top Rail**: Yes
**Anti-Rotational Mechanism**: locks onto the stock barrel nut
**QD Sling Swivel Socket**: No
**Finishing**: Smooth Black hard coat anodized finish
**Blunted machining edges**: Yes
**Removable for maintenance**: Yes

Back in the 80s the US Naval Surface Warfare Center (NSWC) procured SIG Sauer P226 pistols for the SEALs. The NSWC version of the P226 was later sold to the public as the SIG P226 Navy. The Navy has recently given the latest version of their P226 the designation Mk25 and SIG is now selling the Mk25 to public. It is the one with the anchor logo on the slide.

Mossie Tactics has developed their new MT 2400 Light mount in a partnership with Battle Comp Enterprises. Battle Comp already has a distribution system, dealers, and a heavy production capacity, so this pairing up makes sense. Combine it with a product which is so straightforward that I’m wondering why I didn’t think of it first, and it looks like they’ve got a winner.






We first got our hands on a prototype a few weeks ago, but the early production model arrived today. The piece is straightforward in how it mounts. By sliding the grooved portion onto the front sight base, the MT 2400 Light Mount snugs into place. The next step is to tighten the lower screw, then the upper screw, and you are done. If you find the mount tips up or down, adjust your screws accordingly.



The application for the MT 2400 Light Mount is that of a railed extension in the 12 o’clock position. It allows a Surefire X300 or similar light to be mounted, while still retaining functionality of the mechanical and electronic sights. Pushing a light farther forward eliminates shadowing from the barrel, and that is always a good thing. The 12 o’clock mounting position with the light means the rocker switches for the little lights can be activated with either hand, and there is less of an issue when shooting around barricades or corners.

Made in the USA from 6061 aluminum, this has a MSRP of $79, which isn’t cheap, but it is a lot less money and weight than a long rail for your weapon.

The Daniel Defense 1 O’clock Offset Rail is optimized for mounting miniature red dot optics in the 1 O’clock (right-hand) or 11 O’clock (left-hand) positions for quick, non-magnified, transitions when employing magnified primary optics on AR-type rifles with MIL-STD-1913 rails. The geometry allows for zero cheek-weld shift during the transition. This facilitates very fast transitions from magnified to non-magnified optics, and back. The 1 O’clock Offset Rail can also be used to mount a variety of lights or other accessories that mount to a MIL-STD-1913 rail. By flipping the part upside-down, one can mount a light in a good position for use with a vertical foregrip.

Kahles scope for the Chinese QBU-88 Designated Marksman Rifle

During a recent police open house in one of the Chinese municipality, the SWAT team’s QBU-88 5.8mm designated marksman rifles had what seems to be the Austrian made Kahles Helia 3-12x56mm rifle scope in an elaborate mount. While it may not be well know in the US, Kahles riflescopes are among the best optics in the world. Actually this is not the first time that I had saw images of the QBU-88 with the Kahles riflescope. There were pictures from over a year ago shown the Chinese paramilitary CAPF (China Armed Police Force) was testing a similar combination at the range.



Before continuing with the Kahles, lets look at what it is replacing. The original standard issued optic for the QBU-88 is the 3-9x40mm illuminated reticle model made by the Pearl River Optronic (aka the State Arsenal 338) in Chengdu, China. The optic design was based on a Swarovski design from the early 1990s. It has three very advanced features at the time. First of those is the Constant Eye-relief through out the zoom range. The second is the First Focal Plane (FFP) reticle, which the reticle size changes according to the magnification. The third is the Bullet Drop Compensation (BDC) reticle in form of a series of small chevrons reticles all the way to 800 meters. The horizontal stadia consist of bracketed line segments in various lengths. Each of those is calibrated for shoulder width human size target at a given distant. Together with the FFP, the shooter can use the reticle for range estimation at any magnification. By design, once the Chinese 3-9x40mm DMR scope is properly zero to the QBU-88, the designated marksman can use it to engage targets at any range up to 800 meters without the need to touch the windage or elevation turret.





While the design concept sounded good on the paper, however, there are a lot of issues on the actual production model. The state owned Chinese optic manufacturer was just couldn’t maintain the quality control on large-scale production. There were reports of canted reticle, lens clarity issues and out of spec QD scope mount. Then, there is also the logistic problem due to the Pearl River Optronic went bankrupt in late 2006.

In the following year and during the preparation of the 2008 Olympic, another shortcoming of the QBU-88’s optic had surfaced. Being designed as a DMR scope, the 3-9x40mm is not suitable for the counter-terrorism role. It lacks the magnification and the optical performance to positively identify a target at the rifle’s effective range. The temporary solution was to purchase a small number of 6-24x44mm scope build by a privately owned small Chinese optic company based in Shenzhen, China. More interestingly, some Swarovski scopes were also imported for use on the QBU-88.

The most interesting part of new configuration with the Kahles scope on the QBU-88 is actually the elaborate optic mount. My good friend and IMO writer, David Fortier, had pointed out the significance of the top rail, its forward location and the box-like support structure around it. While it can be use for a small red-dot sight or a laser designator, the true purpose of the top rail is for mounting a night vision device in front of the Kahles day optic. Most likely they got the idea from LaRue Tactical’s S.T.O.M.P. system and its method of hanging a PVS-22 or 24 in front of the objective lens of the riflescope.

The ARX-160 is an assault rifle manufactured by Pietro Beretta S.p.A.. Developed for the Italian armed forces as part of theSoldato Futuro (Future Soldier in English) program, the ARX-160 has been launched in the year 2008 as a commercial weapon system independent from the Soldato Futuro ensemble, complete with a companion single-shot 40mm NATO low-velocity grenade launcher, called GLX-160, which can be underslung to the rifle or used with an ad-hoc stock system as a stand-alone weapon.



The ARX-160 departs from the previously issued Beretta 70/90 weapon system under several points of view. The weapon is composed of two receivers, both manufactured mostly in polymer, and operates through a short-stroke piston system. Feeding is through STANAG magazines. The weapon's unique features include ambidextrous safeties, magazine catches and charging handle, the ability to change which side spent casings are ejected, a quick-change barrel which can be removed and replaced in seconds without tools, picatinny rails and a foldable telescopic stock. The lightweight barrel is chrome lined and manufactured by the hammer forging process at the Beretta factory in Gardone, Val Trompia, in the Brescia region of northern Italy.
