About a week ago, on January 31, 2011, the U.S. Army issued a Draft Request For Proposal (RFP) W15QKN-11-R-F003 for an “Individual Carbine” to supposedly replace the Colt M4/M4A1 Carbine, a direct-gas-impingement (DGI) AR-15 carbine configured to U.S. military specifications. Of course, the Army looking for an “Individual Carbine”, or “Next Carbine”, as an M4/M4A1 replacement is old news. Let’s not forget that the Army issued Solicitation Number: W15QKN-10-X-0455 for “Small Arms Technology – Individual Carbine” (sound familiar?) on May 27, 2010. That was eight months ago. Before that, on February 6, 2010, almost exactly one year ago, the Army had issued a sources sought notice for a “M4 Carbine Modification Kit” to improve/upgrade the M4/M4A1 Carbine. Sixteen months before that, on August 22, 2008, the Army had issued a sources sought notice for an “Improved Carbine and Subcompact Individual Weapon System”.

So, this whole thing really started two and a half years ago. I’ll cut to the chase. I don’t think the Army is going to replace the M4/M4A1 in the traditional sense of going to a whole new weapons platform (non-AR). I think they’ll perhaps improve/upgrade the current system with various components and coatings and perhaps contract it to multiple manufacturers, but that’s about it. Whatever happens, the end result will most-likely be an improved AR-platform (AR-15 platform) weapon. Here are the potential improvement/upgrade nominees:

1) M4A1 Carbine-Type True Full-Auto Capability and Heavier-Profile Barrel. The M4’s current 3-round burst feature would go the way of the Dodo, as it should. The 3-round burst is not only the worst and dumbest thing about the M4, it also makes for a lousy semi-auto trigger pull. If you’re going to put a burst limiter on a weapon, better to go with a 2-round burst in addition to a full-auto setting, not instead of it. An M4A1/IAR (Infantry Automatic Rifle)-type full-auto capability will require a heavy-profile (or, at least heavier-profile) machine gun barrel

2) Ambidextrous Controls. DefenseReview (DR) recently published info on the AXTS ambi lower receiver (AX556 and AX762), which is a true, full ambi lower. Ambidextrous AR lower receiver controls are hot right now. Smith & Wesson (S&W) is offering ambi controls on their latest M&P AR submissions to the military, and Colt is offering them on their CM901 modular, multi-caliber 7.62mm/5.56mm universal lower receiver (AR lower).

3) Multi-Caliber and Multi-Operating-System Capability/Modularity. The new Colt CM901 7.62mm NATO battle rifle/carbine/SBR (Short Barreled Rifle) that’s convertible into a 5.56mm NATO assault rifle/carbine/SBR is a prime example of this movement. Since the CM901 is an AR platform weapon, you can pre-zero your optics for each caliber and length upper receiver, so you can quickly swap out uppers for different and specific missions. The CM901 will also be an operating system-convertible weapon, in the sense that it can utilize the Colt APC (Advanced Piston Carbine) and Colt AHC (Advanced Hybrid Carbine) systems, in addition to Colt’s legacy DGI system. Or, you can stick an Adams Arms piston-driven AR upper, LWRC piston upper, or POF piston upper on the Colt CM901 lower, if you’d like.

4) Recoil Attenuation/Mitigation Hardware/Technology for better full-auto controllability. A good example of this is the excellent (patented) FERFRANS Rate Reduction System (RRS) a.k.a. Delayed Sear Activation System (DSAS), which DefenseReview has covered extensively in the last few years.

5) Mid-Length Gas System and Barrel. All you need is a mid-length gas tube/barrel setup. The weapon would stay direct-gas-impingement, but the mid-length system would provide for a “smoother-shooting” weapon, where the felt-recoil impulse is spread out over more time.

6) Gas piston/op-rod (operating rod) System/Kit. The simplest and most cost-effective solution that achieves adequate/requisite reliability is probably the Adams Arms (AA) AR-15 Gas Piston System. AA makes both carbine-length and mid-length piston systems. If you’re going to utilize a 14.5-16″ barrel, the mid-length Adams Arms piston system kit seems like the optimum solution, since it’s reportedly smoother-shooting with a lower felt recoil impulse.

However, there are some other potentially viable, if more costly, gas piston/op-rod system solutions for the Individual Carbine, including, but not necessarily limited to the Colt APC (Advanced Piston Carbine) system (short-stroke), Colt AHC (Advanced Hybrid Carbine) system (short stroke); Primary Weapons Systems (PWS) long-stroke piston system, like that used on the PWS Diablo AR SBR); LWRC (also written LWRCi) short stroke piston system, like that used on the LWRC M6A2 (carbine length gas) and M6A3 (mid-length gas) carbines/SBRs; and Patriot Ordnance Factory (POF) FAL-type short-stroke piston system.

The three primary combat-relevant advantages to the gas piston/op-rod system over the direct-gas-impingement system are 1) enhanced reliability with short, sub-12.5″ SBR barrel and muzzle can (silencer/sound suppressor) attached, 2) the “over the beach” capability of being able to fire the weapon immediately after bringing it up out of the water without causing a catastrophic failure, and 3) being able to go more rounds without any cleaning. With a DGI weapon, you have to shake the water out of the barrel in order to be able to safely fire the weapon. It should be noted that a properly sprung and maintained DGI AR carbine/SBR can be fired for thousands of rounds without cleaning.

7) 16″ barrel instead of 14.5″ barrel.  Believe it or not, 16 inches offers just enough of a velocity and range advantage over the 14.5″ barrel to be considered combat-significant by some pretty experienced and knowledgeable people DR knows. Theoretically, the Army could also provide operators with a second/replacement SBR (Short Barreled Rifle) upper receiver with a 10.5-12.5″ barrel, so they can swap out uppers with pre-zero’d combat optics, depending on the mission-specific requirements.

8.) High-Tech Self-Lubricating/Anti-Corrosion Internal Coatings and Protective and Thermal/IR (Infrared) Camouflage External Coatings. The two most popular internal coatings for firearms right now are the FailZero nickel-boron (Ni-B) coating and CerakoteMicro-Slick (also written MicroSlick) ceramic firearm coating. It should be noted that small boutique AR manufacturers like Next Generation Arms (NGA) (maker of the new X7 “Gray Rifle” mid-length DGI AR carbine) and STS Arms have their own internal ceramic coatings for firearms that look pretty good.

While we were at SOFIC 2010, the Smith & Wesson (S&W) M&P AR carbines/SBRs Defense Review viewed and handled sported both FailZero nickel-boron-coated internals AND and what DR understood to be an anti-IR external coating (unconfirmed/unverified).

9) AR Combat Match Trigger. DR contributor Mike Pannone has written about the the advantages provided by a good combat match AR trigger.

10) Monolithic Rail System. Companies like LMT and Colt already offer AR rifles/carbines/SBRs with monolithic Mil-Std-1913 “Picatinny” quad rail systems, and there seems to be a movement toward monolithic rails for the AR rifle platform. A monolithic rail means that the rail system is integral with the upper receiver, i.e., all one piece.

11) Side Charging Handles and Forward Charging Handles. The purpose of this feature would be to improve the weapon’s ergonomics, and thus “usernomics”.

12) Improved/Upgraded Accessories. This might include aftermarket accessories like buttstocks (Vltor IMod, MagPul CTR (Compact/Type Restricted), LMT SOPMOD), flip-up BUIS (Back Up Iron Sights), pistol grips (like TangoDown, MagPul, and ERGO Grip), automatic windshield-wiper-type ejection port dust cover, flash hiders (flash suppressors), etc.

13) Higher-Capacity Magazines. Enhanced-capacity rifle magazines like the SureFire HCM (High Capacity Magazine) 60-shot and 100-shot 4×2 “Quad Stack” mags (box magazines) and Armatac 78-shot SAW-LITE Mag and 150-shot SAW-MAG drum/double-drum mags could be real game changers, particularly if future U.S. Army infantry soldiers/warfighters are able to employ true full-auto fire from their carbines.
