FR-16 Rifle. 16″ Barrel. 15″ M-Lok Rail. Caliber: .223 Remington / 5.56 NATO

Item Description:

FSAAP (through FedArm) introduces the FR series of AR-15 style rifles and pistols. The FR series is our answer to simplifying the AR-15 & M4/M16 platform to achieve automated robotic mass production across multiple variants and calibers.

FR series firearms differ from our AR series through the new FA-27 Alloy receivers, made through our proprietary vacuum molding and machining process which gets us similar 7075 Alloy strength at 15% the cost and 50 times the output capacity per hour. The firearms are simplified by removing forward assist, dust cover, bolt catch, captive pins, and some geometry for weight savings.

Every internal part of the weapon is 100% US DoD Mil-Spec, made 100% in house by FSAAP.
