AR GAS Piston included itemsAR GAS Piston Assembly
GAS Piston Retrofit Kit

The GAS piston assembly kit is now available for short barrels with the following barrel diameters (measured 1.5 inches inbord of the site): 0.875, 0.850, or 0.640. This covers most barrels in the 16" barrel range including the M4. The system uses a low-pressure, long-stroke gas piston design to keep from "hammering" the bolt as the short stroke designs do. The result is less shock forces on the system, longer lasting parts and reliable feeding. It's the difference between unlocking your bolt with a ball peen hammer or accelerating it on a cushion of air! Kit includes: handguards, gas piston assembly, gas key, and all hardware. Includes all items pictured in left picture. Does not include barrelled upper. Nickel Plated Kit....$275.00
