Adams Arms Low Mass AR15 Piston Bolt Carrier AR-15
This new low mass carrier is compatible with mil-spec upper receivers and is rated for full auto. This one-piece bolt carrier is proprietary in design to be used with the Adams Arms piston system and is 21% lighter than our standard piston bolt carrier. The design of this carrier is perfect for special projects where tuning the weapon is mandatory or adapting for limited gas pressure is required. This allows starting with a smaller gas port, which will help in reducing recoil and make for better shot acquisition. This also allows running with lower pressure ammunition.
