H.C.A.R. - Ohio Ordnance

The HCAR is a modernized version of the M1918 BAR, with improvements such as adjustable stock, 45-degree selector switch, takedown pins, bolt hold open, picatinny rails and carbon fiber trigger section. It also features an adjustable gas regulator (3-position) for suppressors, and a hydraulic buffer. It comes with either a 16″ barrel or 20″ barrel, with a 1/10 rifling twist rate and a 5/8-24 muzzle threading. The barrel is free-floated for better precision.

The HCAR fires from a closed bolt, is gas-operated with a long stroke piston, and is fully compatible with any AR-15-style stock.
