This Drill Fixture will allow you to finish the machining process for our Billet Ar 15 80% Lower to include the FCG (Fire Control Group) Pocket, Hammer and Trigger Pin Holes and Safety Selector Hole.

Drill Fixture Contents:

Our 4-piece 80% Lower Jigs include the following:

  • Left Hand and Right Hand Side Plates
  • Drilling/Trigger Slot Top Plate
  • Milling Top Plate
  • Needed Fasteners

Jig Compatibility:

Our Lower Jig is designed specifically to fit our Billet AR 15 80% Lowers. It will also work well on many other Billet AR 15 80% Lowers as well as many Forged Lowers. And since we hold very tight tolerances on our Lowers, our Lower Jig will NOT work with 80% Lowers that are “under spec” in width of 0.906″ wide at the FCG.

One aspect of our Drill Jigs that is unique to our Billet AR-15 80% Lowers is that we have already milled the Upper Rear/Take Down Lug Pocket of the Lower so it is not a part of our Jigs.
