The 80% Lower Jig will allow you to finish machining our billet 80 percent receiver to include the FCG (Fire Control Group) Pocket, Hammer and Trigger Pin Holes and Safety Selector Hole.

 Drill Fixture Contents:

The 4-piece 80% Jig Kits include the following:

  • (1) AR 10 308 80% Lower Gen.1 Raw
  • Drilling & Trigger Slot Top Plate
  • Left Hand and Right Hand Side Plates
  • Drilling & Trigger Slot Top Plate
  • Milling & Rear Pocket Top Plate

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.
