Adams Arms Standard Picatinny Piston Kit AR-15 Rifle Length Gas System Upgrade

The Adams Arms Standard Picatinny Piston Kit for AR-15 Rifle Length offers a high-performance gas-system upgrade designed to work with .223/5.56 x 45 mm NATO platforms, delivering reliable operation and enhanced cleanliness. This kit includes a patented One-Piece Bolt Carrier, a .750" Picatinny gas block with three adjustable settings for full gas, half gas for suppressed, or no gas for single-shot applications, along with a gas plug, bolt spring, drive rod with bushing and spring, and an installation instruction card, all engineered to streamline installation by no longer requiring a receiver bushing or installation dowel. The Adams Arms piston system features a short-stroke, free-floating piston that is self-cleaning, with carbon and gases expelled forward away from the operator, and a corrosion-resistant coating that withstands rigorous use. Its design prevents harmonics from transferring into the barrel, while adjustable gas settings accommodate various applications and suppressors. Importantly, the system does not vent directly to atmospheric pressure, reducing flash signature and sonic crack for night vision compatibility and overall stealth. From the barrel extension to the shoulder, this kit measures 13.241 inches, delivering a robust upgrade to AR-15 rifle gas performance and reliability.
