Viper Defense presents our Gen 3 AR 15 80% Lower Receiver Drill Jig which is machined from 6061-T651 Aircraft Grade Aluminum. This Drill Jig 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 5-piece 80% Lower Drill Jig Kits include the following:

  • Left Hand and Right Hand Side Plates
  • Drilling Top Plate
  • Milling Top Plate
  • Trigger Slot Drill-Mill Top Plate
Jig Compatibility

Our Drill Jig is designed specifically to fit our Billet AR 15 80% Lowers. It will also work well on many other AR 15 Billet Lowers as well as Castings, but NOT many Forged Lowers since virtually none of them are to "width spec", and they have to be 0.906" wide at the FCG in order to have our tight tolerance Drill Jig fit correctly.

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.

Jig Finish

Our Drill Jigs are now Anodized Blue (or soon will be) in the "Raw" state directly from our CNC machines and they are deburred only.

Customer Reviews
Rating 80% Jigs
These jigs are very simple to use in completing the 80% lower. I was skeptical at first but when they arrived everything made since and it was eazie peezie. Just lay the side plats on and screw the top jig down and your set. Do not be afraid to try this on your own.
