Jig Compatibility:

Our Jig is designed specifically to fit our Billet AR 10- .308 80% Lowers. It will also work well on many other Billet AR 10- .308 DPMS, Gen. 1, Lowers. One aspect of our Jigs, that is unique to our Receivers, is that we have already milled the Upper Rear Pocket of the Lower so it is not a part of our Jigs.
