Firearms with a direct impingement design can, in principle, be constructed lighter than piston-operated designs. Because high-pressure gas acts directly upon the bolt and carrier in a direct impingement system, it does not need a separate gas cylinder, piston, and operating rod assembly of a conventional piston-operated system, only requiring a gas tube to channel gas from the barrel back ...
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.
Chamber-ring-delayed blowback . When a cartridge is fired, the case expands to seal the sides of the chamber. This seal prevents high-pressure gas from escaping into the action of the gun. Because a conventional chamber is slightly oversized, an unfired cartridge will enter freely.
short-stroke gas piston Short stroke gas piston and bolt carrier group, from a gas piston AR-15. With a short-stroke or tappet system, the piston moves separately from the bolt group. It may directly push [12] the bolt group parts, as in the M1 carbine, or operate through a connecting rod or assembly, as in the Armalite AR-18 or the SKS.
