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 series 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 features Kel-Tec's new waffle pattern design.

This model is chambered in 9x19mm Luger and features an olive drab green color pattern and threaded barrel. It accepts Glock-style magazines and includes one 17-round magazine.
