The Kel-Tec SUB2000 Gen3 in 10mm Auto delivers a compact, folding pistol-caliber carbine built around Glock 20 magazine compatibility, giving shooters access to standard, extended, and high-capacity magazine options. Chambered in 10mm Auto and built with a 16.15-inch threaded barrel, it provides strong ballistic performance in a lightweight, easy-handling configuration. The Gen3 design incorporates a rotating forend that allows the carbine to fold in half while keeping mounted optics in place, creating a highly portable platform for storage or transport. Its tan receiver includes top and bottom Picatinny rail sections, and the M-LOK handguard supports additional accessories for a tailored setup. The tan polymer stock maintains a streamlined, durable profile, while the Glock 20 grip ensures magazine compatibility and familiar ergonomics. Adjustable sights, an optics-ready layout, and a threaded muzzle add versatility for a wide range of shooting applications. Built for shooters seeking a powerful pistol-caliber system with modern folding capability, the SUB2000 Gen3 combines portability, modularity, and dependable performance in a 10mm-ready package.
