The Sub2000 is a general-purpose pistol-caliber carbine designed for a variety of uses from target shooting to personal protection. The rifle's signature feature is a collapsible design that reduces the rifle's length by half and allows for easy storage in small spaces. The addition of a full polymer frame also keeps the rifle's weight under 5 pounds while improving corrosion resistance against the elements. The Gen2 model features an 3-position adjustable stock and an M-LOK/picatinny rail combo handguard for mounting lights, grips, and optics. The ejection port has also been enlarged for improved reliability and the grip feature's Kel-Tec's new waffle pattern design. This model features an olive drab green color pattern and a threaded barrel. It is chambered in .40 Smith & Wesson and compatible with M&P magazines. One 15-round magazine is included.
