The Just Right Carbines Gen 3 JRC9G3-TB/BL is a 9mm semi-automatic rifle built around a straight-blowback operating system and standard Glock magazine compatibility. Its 17-inch button-rifled barrel features a 1/2x28 threaded muzzle, while the 13-inch free-float KeyMod handguard provides a flexible mounting surface. A machined Picatinny top rail supports the addition of an optic. The carbine uses a standard M4 buffer tube, six-position adjustable buttstock, pistol grip, and compatible AR-15 furniture and trigger components. Ambidextrous bolt and ejection configurations allow the rifle to be set up for either side.
