10" HD Hardened Quad Rail w/barrel nut and screws
Your Price $79.99
Hardened Arms LLC, Quad rails are manufactured in-house and 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 this rail is designed to accommodate the majority of suppressors available in the marketplace. Built to fit the same barrel nut as our TLN, Featherweight Scorpion and LumaShark(R) rails, it attaches with a unique alignment lockup dovetail and eight allen head screws. With a superior fit and anodized finish these quad rails are a great starting point for your  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 and tightening to a torque value between 30ft/lb and 70ft/lb with a tighten and release install, three times before final indexing. Built from 6061-T6 aircraft aluminum with level III hard anodizing this rail is designed to fit your 10-16" barrel with a pistol or carbine length gas system.
