Precisely machine your AR9 80% lower with the right tools and jig.
Completing your AR9 or 9mm PCC build means getting the 80% lower cut and drilled just right. These new receiver blanks work with AR-15 lower parts kits, though their external shape and dimensions differ slightly because of their proprietary design and smaller, Glock-compatible mag well. To ensure proper fitment and cutting of the fire control cavity for the LPK, it is recommended you select one of the AR9 jigs above. Each jig includes the necessary tooling (drill bits and end mill bits) to complete your lower for final assembly.
