The Alpha Stock is versatile enough to work with any AR build. It features a low profile adjustment latch, double injected rubber cheek rest, and slick sided profile. The butt-pad profile is angled to accommodate plate carriers and the aggressive texturing will ensure minimal movement when manipulating the rifle under stress. For your safety, Trinity Force recommends this part be installed by a competent, qualified gunsmith/installer with an understanding of the weapon platform that the part is being installed on. Always make sure the firearm is unloaded and pointed in a safe direction when working.
