The GMR-15 9mm is a versatile platform that excels in both function and accuracy. Complete carbine builds are available with either our forged JP-15™ or PSC-17™ dual-charging upper that includes our 9mm Silent Captured Spring standard. The end result is a system that cycles with virtually no recoil. That equates to extremely fast sight recovery with accuracy from a pistol cartridge usable out to 100 yards. With the high-performance ammunition available from many manufacturers, the GMR-15 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 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.
