Meet the JP Enterprises GMR-15 Ultralight Ready Rifle chambered in 9mm with a 5.5" pinned and welded barrel shroud. This lightweight, competition-focused PCC combines a top-charge forged upper with a billet lower to create an exceptionally balanced and fast-handling platform that meets legal rifle length requirements at 16.5" overall barrel length. The JP Supermatch ultralight barrel with 1:10 twist delivers outstanding accuracy and reliable feeding with a wide range of 9mm ammunition. Equipped with a 12.5" M-Lok handguard, Gen 2 Silent Captured Spring System (5 steel short stroke), polished stainless short-stroke bolt carrier, and a crisp 3.0-3.5 lb competition trigger, this rifle offers minimal recoil and lightning-fast follow-up shots. Premium controls include the Radian Raptor-LT ambidextrous charging handle, extended magazine release, reversible full-throw safety with modular levers, Mission First Tactical Battlelink Minimalist stock, and Hogue pistol grip for superior ergonomics during extended match days or range sessions. Built for shooters who want maximum speed and minimum weight without sacrificing reliability, the GMR-15 Ultralight is ideal for Steel Challenge, PCC competitions, and high-volume training. It comes complete with a Glock 10-round magazine and is ready to perform straight from the box.
