Sons Of Liberty Gun Works LOYAL9 Stripped Lower Receiver Features The Sons Of Liberty Gun Works LOYAL9 lower receiver is forged from 7075-T6 aluminum providing the strength and durability needed as the serialized core of a semi-automatic 5.56 NATO or .223 Remington AR build. A Type II hardcoat anodized finish with a bright dip process gives the receiver a deep consistent black coating that resists corrosion and wear through heavy use. The receiver is fully machined to remove forging flash marks delivering a cleaner finished surface than many entry-level lowers provide straight off the forging line. Built to mil-spec M4 dimensions the LOYAL9 accepts standard AR-15 lower parts kits stocks and pistol grips without fitting issues. A low rear shelf design offers improved compatibility with certain buffer tube and stock combinations. The receiver includes an M16 pocket cutout a common feature on quality AR-15 lowers that supports additional fire control group options for properly licensed builders. Loyal 9 logo roll marks and Safe-Semi-Auto selector engravings give the receiver a distinct identity beyond a generic mil-spec lower. For builders who want a well-finished semi-automatic 5.56/.223 lower receiver with real character the Sons Of Liberty Gun Works LOYAL9 is available for sale at GrabAGun.
