JP Enterprises GMR-13

Available as a complete carbine, upper or lower assembly, the newly released JPGMR-13 9mm is a versatile platform that measures up in terms of both function and accuracy. Built on either JP-15 or PSC-11 upper receiver, this blowback-operated carbine cycles with virtually no recoil and allows 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 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. 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.
