The JRC Rail Model carbine in .45 ACP (part no. JRC45G3-TB/BL) from Just Right Carbines is a black, 17-inch threaded-barrel pistol-caliber carbine that feeds from Glock-pattern magazines. The rail-forend version carries a 13-inch handguard with a short accessory rail for lights and lasers. The receiver is machined from one piece of 6061-T6 aluminum, and the controls follow the AR layout with ambidextrous ejection and charging options.
