Overview

The receiver set uses forged 7075 T6 aluminum, while the handguard is a free-float M-Lok design that reduces weight and provides modular accessory attachment. The pistol is equipped with a carbine-length gas system and a low-profile gas block, ensuring reliable cycling even with suppressed subsonic loads.
