The KelTec SUB2000 Gen 3 5.7x28mm Tan is a folding semi-automatic carbine with an optic-ready design and a 16.1-inch barrel (KelTec part no. SUB2K57TAN). KelTec calls the third generation the one that folds in half with the optic still on it, and the rotating forend is what makes that work. A straight blowback action keeps the carbine simple to run and maintain, while the adjustable stock and tool-free field stripping make it easy to set up and clean. Chambered in 5.7x28mm and fed from FN Five-seveN magazines, it is a compact option for the range, trunk or truck gun.

Key Specifications
