80% Raw - Billet Lower Receiver

Description: Cut from a solid block of 7075-T6 aerospace grade aluminum. These 80 lowers start from one of the best materials available. The 80 lower is tumbled and deburred with a natural finish. Our AR15 80 lowers include an upper tensioning set screw hole to tighten the upper and lower fit to your liking. These lowers also have a built-in trigger guard. The magazine well is broached for consistent magwells from part to part. If looking to build something other than your standard 5.56mm AR-15 build we have a compatibility list.
