JP AR15 9mm Lower Receiver Kit GMR 13
The JP AR15 9mm Lower Receiver Kit GMR 13 is a great starting point for a new 9mm build. By accepting Glock G17 9mm magazines, this lower allows for the ultimate in sidearm & rifle compatibility. Combined with the JP 9mm AR-15 Bolt Carrier and Silent Captured Spring, you can have a unique 9mm build running smoothly and reliably. The lower fits standard AR-15 upper receivers, as well as grips, triggers and buttstocks. Large magazine release allows for quick magazine changes. Receiver includes magazine catch, ejector, bolt catch and necessary pins & springs. Does not include trigger group.
For the home builder with a 9mm project, this GMR-13 billet lower receiver accepts Glock G17 magazines and will mate to any Mil-spec compatible upper receiver. This kit includes all exclusive mag. catch, bolt catch and ejector components required for function.
About the GMR-13 Platform – courtesy JP Rifles
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.
