Definitions

  • This invention relates in general to automatic and semi-automatic hand weapons and more particularly to submachine guns. Still more particularly, this invention relates to submachine guns having elements and subasse blies which are easily interchangeable at the field level.
  • Submachine guns are well known in the prior art. Several well known examples of such weapons are manufactured by Thompson, UZI and Ingram. Most of the well known submachine guns are fired by the operator using both hands to control the weapon. In each instance, these known designs provide a pistol grip for the trigger finger and a forearm grip or straps for the second hand to hold onto and secure the weapon. Cartridge case rejection of these weapons is fixed at a single point such that empty cartridge cases are ejected away from a right-handed firer. Consequently, a left-handed firer frequently finds himself hit in the upper torso and face with one or more hot cartridge cases which are being ejected from such standard weapons.
  • the submachine gun includes a barrel threaded into a muzzle nut and a breech assembly.
  • a forward housing surrounds the barrel and a forward bolt and includes dovetail slots for receiving a grip assembly and the cocking mechanism.
  • a rear housing comprising two nested tubular members is utilized to receive and restrain a selected magazine housing and the rear housing and forward housing are rotatably coupled at the breech assembly to permit the magazine and grip assembly to rotate independently to multiple firing positions.
