This is an AR9 that I built a while ago, and I'm ready to sell. Upper is Knight's Amrament (16" barrel) with a Midwest Industries hand guard, BCM grip, Aero EPC-9 lower, milspec trigger, Adaptive polymer hand grip, UTG stock. Comes with UTG and ProMag 30rd Glock mags. Asking $600. Will meet locally at a range to test fire (I'll provide an optic and 10 range rounds for firing). Cash, Apple Pay, or Venmo accepted.
