Hardened Arms Quad rails feature a full picatinny at 12:00, 3:00, 6:00, and 9:00 to provide for every accessory. With an interior circumference of 1.80 it is designed to accommodate most suppressors available in the marketplace. Built to fit our the same barrel nut as our TLN, Scorpions and LumaShark rails it attaches with eight allen head screws. With a contoured back feature to the picatinny these quad rails are a great starting point for your next AR build. Quad rails come with an aluminum barrel nut and mounting screws. We recommend greasing the barrel nut before installing on your upper receiver to a torque value between 30ft/lb and 80ft/lb three times before final indexing. Built from 6061-T6 aircraft aluminum with level III hard anodizing this rail is designed to fit your 12.5+" barrel with a pistol, carbine or mid-length gas system.
