GMR-15 9mm Carbine

The GMR-15 is an updated version of JP's industry-leading 9mm carbine the GMR-13. It’s loaded with innovative features that elevate the pistol caliber carbine platform.

First, they started with a ground-up revision of the lower receiver. It features last-round lockback and a streamlined look.  An upgraded mag release offers better leverage and an improved feel.  JP also flared the magwell more than on the GMR-13 for easier reloads.

They also designed a new, dedicated 9mm upper receiver with dual-charge handles that's much lighter and sleeker than the PSC-11 which was used on the dual-charge version of the GMR-13.  This upper comes with a choice of brass deflectors, including a larger-profile version for left-handed shooters.

Customers can buy complete GMR-15 rifles that are fully customizable in JP’s online Rifle Builder. Complete rifles offer the choice of three uppers, the dedicated 9mm upper, the JP-15 forged upper or the CTR-02 top-charge billet upper. For speedier delivery, JP Enterprises will offer two GMR-15 Ready Rifles: a 14.5" pin-and-weld and an SBR.
