Jig Compatibility:

Our Lower Jig is designed specifically to fit our Billet .308 80% Lowers. It will also work well on many other Billet .308 DPMS Gen 1 style 80% Lowers as well as many Forged Lowers even though most of them are NOT to “width spec” of 0.906″ wide at the FCG.

One aspect of our Drill Jigs that is unique to our 80% Lower is that we have already milled the Upper Rear Pocket of the Lower so it is not a part of our Jigs.

Our 80% Lower Receiver Jigs are shipped in the ‘Raw’ state directly from our CNC machines and they are deburred only.

You can review our 80% Lower Receiver Jig Instructions to better understand the Drilling and Milling Procedure.
