The skeleton stock is versatile enough to work with any AR build. It features a low profile adjustment latch, angled rubber buttpad, 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, MCS 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.
