308 80% Lower Kits

80Lowers builds Precision Quality 308 80% Receiver & Jig Kits that are CNC Machined from Billet Aluminum. An 308 80% Lower & Jig Kit contains both the needed Part and Fixture that is used by the Customer to complete an 308 80% Lower Receiver, which is the starting point of your custom Rifle Build.

Our original design 308 80% Lower Jigs are still small and compact 4- or 5-piece fixtures including a top Drill Plate that allows most of the material removal to happen with down-force drilling action so it can be completed on a standard Drill Press with a decent vise. Our 80% Lower Receivers also have the Rear Pocket already machined for you, and our 80% Lower Receiver Jig reflects this condition as well.

Benefits of an 308 80% Lower & Jig Kit:

– Both the 308 80% Lower and Jig in one Package
– A Tool Kit can be Added for Complete Convenience
– Upper Rear Pocket Already Completed
– CNC machined from Aero-Space Grade Billet Aluminum
– Simple 4- or 5- Piece 80% Drill Jig Design
– Made by Us Right Here in the USA
