IWI UZI 45ACP w/Registered Bolt

IWI UZI 45ACP w/Registered Bolt

The Uzi is a relatively lightweight weapon. The receiver is stamped sheet metal. Despite its weight, even when fired in full auto, it is very controllable and fairly accurate. The weapon features either a collapsible stock or a wooden stock (though weapons with the latter are rare). It is a blowback-operated weapon, with a telescoping bolt (in which the bolt wraps around the breech) and fires from an open bolt. The breech is not mechanically locked; however, the breech block is heavy enough to prevent the breech from opening until gas pressure in the barrel has fallen significantly. The firing pin does not float freely in the bolt.

The SMG-sized Uzi model features a 10.5 inch barrel; other models generally feature shorter barrels, though the Title 1 variation (the variant legal to sell to U.S. citizens without NFA paperwork) features a longer 16-inch barrel, and fires from a closed bolt. The bolt will close on an empty chamber when the magazine is emptied. The magazine release is on the bottom of the pistol grip.
