Introducing the dedicated 9mm 80% Lower Receiver
This 80% 9mm lower receiver is fabricated to use Glock® (G17 and G19) 9mm magazines out of the box. No 9mm conversion blocks or custom components necessary!
CNC’d from 6061-T6 billet aluminum, this receiver blank features enlarged mag well ramps for quick and easy reloads. We’ve left this lower raw — unfinished, with no coating, so you can apply your own, custom finish.
