Viper Defense presents our new Gen2 AR 15 80% Lower Receiver Drill and Milling Jig which is machined from Aircraft Grade Aluminum. 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 AR 15 80% Lower Drill Jig includes the Left Hand and Right Hand Side Plates, the Drilling Top Plate, the Milling Top Plate and the Trigger Slot Drill-Mill Top Plate.

Jig Compatibility
We created a compact Drill Fixture design shooting for something that was a bit more "universal" than others. Our Drill Jig is designed specifically to fit our Billet AR 15 80% Lowers. We believe that it will also work well on many other AR 15 Forgings as well as Castings.

Please contact us before ordering if you are uncertain that our Drill Jig will be compatible with your 80% Lower. We have adopted a no-returns policy on the Drill Jigs.

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

Jig Finish
Our Drill Jigs are in a "Raw" state directly from our CNC machines and they are debured only. We do not Anodize our 80% Lower Drill Jigs at this time since they are basically disposable tools.

Availability / Shipping
Our Drill Jigs are in stock most days and can be shipped within 2-3 days by USPS Priority Mail. Shipping is set at $7 for one Part and $12 for 2 or more Parts.
