SUB-2000

The SUB-2000 is a pistol-caliber carbine manufactured by Kel-Tec CNC Industries of Cocoa, Florida, United States. The rifle is a blowback operated, semi-automatic firearm with its operating spring located in the tubular stock. The weapon feeds from a grip-located magazine well, using magazines designed for popular models of various other manufacturer's handguns, and is an inexpensive carbine. The distinguishing characteristic of this rifle is that it folds in half, for storage and transportation, and its slim profile compared to other rifles. The benefit of the weapon accepting magazines made for other manufacturer's popular handguns is so the user can choose a version of the weapon that allows them to share magazines and ammunition between both the user's sidearm and the Sub-2000 carbine. The main advantages of a carbine in a pistol caliber over a handgun include the increased sight radius which aids with accurate shooting; the long barrel more efficiently captures burning powder which increases projectile velocity; and more points of contact between the shooter and weapon which increases stability.
