JP GMR15 9mm Billet Lower Receiver
For the home builder with a 9mm Pistol Caliber Carbine project, this GMR-15™ billet lower receiver accepts Glock G17 magazines and will mate to any Mil-spec compatible upper receiver. This is one of the few, if not the only AR9 lower that has a reliable last round bolt open feature.
Don't forget, we offer a layaway program for your convenience. Contact us for details.
This kit includes all proprietary bolt catch, magazine catch and ejector components required for function.
