The SUB-2000 is a self-loading carbine for pistol cartridges. Different versions of the SUB-2000 will accept most modern handgun magazines; The SUB-2000 has a greatly enhanced accuracy and extended range compared to a handgun. The superior precision is also very useful against small or partially covered targets at shorter range. The amount of training to master the SUB-2000 is only a fraction of that required for a handgun. The SUB RIFLE-2000 has been developed from our highly successful SUB-9 rifle. Although retaining some features of the old rifle, the SUB-2000 is a completely new design. Emphasis has been put on consumer safety, but without impeding the performance. Polymers are used to a large extent, resulting in increased durability and reduced price. The SUB-2000 is available in 9 mm Luger or .40 S&W calibers.
