The Barrett REC7 (designation stands for “reliability-enhanced carbine” 2007) is a M4-pattern rifle available in either 5.56 NATO or 6.8 SPC. The REC7 is manufactured by Barrett Firearms Company.
The REC7 is Barrett’s second AR-pattern rifle chambered for the 6.8 mm Remington SPC cartridge, the first being the Barrett M468 rifle. The 6.8 SPC-chambered M468 rifle employed the same direct gas-impingement system as the M4. The result was a system that jetted hot gases directly into the rifle’s receiver, leading to potential stoppages if regular maintenance and cleaning protocols were overlooked. To enhance potential mechanical reliability, Barrett incorporated a short-stroke, piston-driven system that offers the potential for cleaner and cooler operation than one with direct gas-impingement. Barrett are still selling its limited stock of the M468 but only as an upper receiver kit and not as a complete rifle.
Unlike possible replacements for the M16/M4 such as the now canceled XM8, the REC7 is not an entirely new rifle, instead it is made up of an upper receiver that is attached to a M16/M4 lower receiver and is compatible with many accessories intended for the M16/M4 family. It can also be mated to M16/M4 lower receivers currently in the possession of the US military. The rifle uses a short-stroke gas piston mechanism, unlike the M16 or M4 which use direct impingement.In addition, the REC7 uses the new 6.8 mm Remington SPC (6.8 × 43 mm) cartridge, a round that is of roughly equivalent length to 5.56 mm ammunition, so it is compatible with a standard-size lower receiver currently in use by the United States military. According to Barrett, the new 6.8 mm round boasts 44% more kinetic energy than the 5.56 mm round at ranges of 100 to 200 meters and a longer effective range. The company claims that it is effective at five hundred meters and has a muzzle velocity of 2650 feet per second when fired from a 16 inch barrel.
The REC7 uses a short-stroke gas piston designed by Barrett. It rides above the barrel and is housed inside the fore-end. The spring-loaded piston is a one-piece 17-4 stainless steel rod. The forward and rearward movement of the piston is approximately one inch.
Like many AR-15 type rifles, such as the M16/M4, the barrel is threaded to allow muzzle attachments such as a suppressor; it can also use M16/M4 bayonets on its muzzle, such as the M9 Bayonet or OKC-3S Bayonet. The REC7 employs a free-floated Daniel Defense rail system, which allows many military accessories such as a bipod, night vision devices, and combat optics to be placed on the rifle. The REC7 features forged 7075 aluminum upper and lower receivers that are hard-coat anodized a deep black. The lower receiver has a single-stage trigger, a Magpul enhanced trigger guard for firing with gloves, and a beveled magazine well for rapid magazine changes. The upper receiver is flat-top with a Picatinny rail. The barrel is chrome-lined and is fitted with a M16A2-style birdcage muzzle brake and pistol grip. The stock is a six-position Magpul MOE.
