AR Buffer Assembly Kit Black for AR-15
by Trinity Force

The Trinity Force Mil-Spec 6-position receiver extension assembly is made 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, 3oz carbine buffer, a castle nut and lower receiver end plate are included. This assembly kit is suitable for all Mil-Spec AR 15 lower receivers and is compatible with most AR 308/AR 10 rifles but requires a modified buffer and spring for proper operation.
