The Mil-spec Receiver Extension Kit is constructed from aircraft grade aluminum with rolled threading. The buffer tube has been hard coat anodized for maximum corrosion and wear resistance. A standard buffer spring and 3oz carbine buffer are included as well as a castle nut and lower receiver end plate.This assembly kit will fit on all Mil-Spec lower receivers. It is also compatible with most A - R 308/A - R 10 rifles but requires a modified buffer and spring for proper operation.
For your safety, we 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.
