Adams Arms Gas Piston Conversion Lightweight Retrofit Kit AR-15 Mid Length with .625" Diameter Low Profile Gas Block
- Videos (3)
The gas piston kit installs easily, requiring no permanent alterations to the rifle, and adds a minimal amount of weight to the gun over a standard direct impingement operating system. The kit comes complete with a replacement low profile gas block, gas piston, piston return spring, operating rod, solid steel 1-piece bolt carrier, installation hardware and complete instructions. The 1-piece bolt carrier features an integrally machined, solid steel strike face to absorb the operating rod's energy, as opposed to the modified bolt carrier key provided with other conversion kits that relies upon a weaker carrier key screw attachment method. The low profile of the Adams Arms piston design makes it compatible with some free-floating handguards; however removal of some material from the upper portion of the free-float handguard may be required for use with this operating system.
