Self-loading carbine for pistol cartridges. Different versions of the SUB-2000 will accept most modern handgun magazines. Bolt can be locked in the rear position by the operating handle. Main safety is of protected push bolt type disconnecting the trigger bar and interlocking the hammer and sear. By rotating the barrel upwards and back, the SUB-2000 can be reduced to a size of 16x7 inches to facilitate secure storage and utilize the internal deployment lock which is operated by a proprietary key. Rear sight is of aperture type and the fluorescent front sight can be adjusted for windage and elevation. SUB-2000 can easily be disassembled for cleaning or inspection without tools.
