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 wears resistance. Standard buffer spring and 3oz 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.
