Description
Trinity Force AR-15 Receiver Extension Buffer Tube Kit – Black
The Trinity Force AR-15 Receiver Extension Kit (MNTLU04B) 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 3 oz carbine buffer are included as well as a castle nut and lower receiver endplate. 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.
