The KelTec SUB2000 .40 S&W semi-auto rifle (KelTec part no. SUB2K40GLK23BGRN) is built to run Glock 23 magazines, letting shooters who already carry a Glock 23 pistol share magazines with this folding carbine. Finished in blued metal with a green polymer stock, this SUB2000 keeps the fold-in-half portability the platform is known for while delivering the extra reach and velocity a 16.1-inch barrel adds to .40 S&W.
