Compact, accurate and completely trustworthy, the REC7 is designed specifically for situations in which there's no room for error. The REC7 rifle's dependability stems largely from its innovative operating system. Using a minimum number of parts, the piston system separates heat and powder residue from the bolt carrier and trigger assembly. The patented chrome-lined fluted gas block prevents excessive carbon buildup from operation under adverse conditions. The one-piece 17-4 stainless piston transfers energy to the anti-tilt bolt carrier. Machined from a monolithic block of 8620 steel, the carrier features an integral piston strike face. The Barrett Enhanced Bolt is made from high-strength 9310 steel. The bolt is designed specifically for use in the piston operated REC7, not just adapted from a direct gas bolt. The bolt's gas-ring-free design is easy to clean. Reinforced at critical areas, every bolt is proofed and magnetic-particle inspected to guarantee reliable performance. At the heart of the operating system is a nitrided, two-position, forward-venting gas plug that retains the piston. The piston can be accessed through the front of the gas block without removing the handguard so optical sights or laser devices do not need to be zeroed after routine maintenance.
