  • JP PSC-11 Upper 9mm


    Whether as a complete carbine, upper or lower assembly, the GMR-13™ 9mm is a versatile platform that excels in both function and accuracy. The GMR-13™ is available with either our JP-15™ or PSC-11™ upper receiver for a blowback-operated carbine that includes our 9mm Silent Captured Spring standard. The end result is a system that cycles with virtually no recoil, allowing for extremely fast sight recovery with solid 3 MOA accuracy from a pistol cartridge usable out to 100 yards.

    With the high-performance ammunition available from many manufacturers, the GMR-13™ makes a solid choice for a competitive match carbine (especially considering the cost savings of 9mm ammo over .223) and is also well-suited to home defense applications given its impressive .357 magnum-comparable ballistics with a carbine-length barrel. The lack of concussion in enclosed spaces and greatly limited over-penetration issues when compared to most rifle cartridges only enhance its suitability in this arena.

    Designed from the start with the needs of law enforcement in mind, the GMR-13™ accepts the same G17 pistol magazines as Glock 9mm pistols for carbine/sidearm compatibility and is also available in select-fire configurations. Built on the PSC-11™ upper receiver platform with its dual charging systems, the GMR-13™ readily accommodates those with training backgrounds on either the HK or AR-15 platform. Also available for military and law enforcement, the complete rifle package includes our own JP select-fire trigger setup for precision trigger control in both semi- and full-auto modes. As with all JP rifles, the GMR-13™ comes with parts and service readily available from a trusted US manufacturer.
