AR Receiver Extension Kit

The AR 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 AR 15 lower receivers. It is also compatible with most AR 308/AR 10 rifles but requires a modified buffer and spring for proper operation.

 

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.
