An Adams Arms piston is a gas piston conversion system designed for AR-15 and AR-10 rifles, replacing the traditional direct impingement system for cleaner, more reliable operation. It includes a piston-driven gas block, operating rod, and related hardware. The Adams Arms piston works with AR-15/AR-10 barrels, upper receivers, compatible bolt carrier groups, handguards, and gas tubes. It’s ideal for shooters seeking reduced fouling, improved reliability, and easier maintenance in their AR-platform builds.
