The Kel-Tec SUB-2000 Gen3 is a folding 9mm carbine built to pick up where your handgun leaves off. It folds completely in half - optics and all - for compact storage, then deploys quickly when you need it. This GLK model runs both Glock 19 and Glock 17 magazines, and a rotating forend keeps a mounted optic zeroed and ready with a single-handed motion, so you can put it on and leave it on. A straight blowback system keeps operation and maintenance simple, the stock adjusts to fit the shooter, and the 16.15" barrel wrings extra velocity and downrange power out of pistol-caliber ammunition. M-LOK slots and Picatinny rail space on top and bottom keep the platform ready for lights, optics, and other accessories. 9x19mm, accepts Glock 19 and Glock 17 magazines Folds in half for compact storage and transport Rotating forend keeps optics mounted, zeroed, and ready 16.15" barrel for added velocity and downrange power Straight blowback action for simple, reliable operation Adjustable stock Tool-free disassembly for cleaning and inspection M-LOK compatible with Picatinny rail space top and bottom Black finish
