Workpieces for producing a firearm have an elongated body defined within a cross-sectional profile with a first elongated passage configured to receive the upper portion of the bolt, and with a second elongated passage configured to receive the lower portion of the bolt, and the elongated body having a separator between the first elongated passage and the second elongated passage and configured to prevent installation of the bolt assembly when the separator is present, and to enable installation of the bolt assembly when the separator is absent. The cross-sectional profile may be along the entire length of the elongated body. The cross-sectional profile may fully encompass the first elongated passage. The first elongated passage may be open only at the ends of the elongated body. The cross-sectional profile may have a U-shaped cross-section.

Various embodiments are directed to systems, apparatus and methods configured for anthropometrics data/measurement acquisition such as for fitment of handguns, hand tools, weapons and the like.

A fully automatic small arms demilitarization system includes individual infeed conveyance systems loaded at a single process initiation location; multiple hydraulic press stations fed by the individual infeed conveyance systems; and the multiple hydraulic press stations configured to crush one section of each weapon per cycle, incrementally crushing an entire length of each weapon, completely distorting each weapon to preclude restoration to a useable condition. The system further including an output system configured to output demilitarized weapons onto a common outfeed conveyance system that delivers the demilitarized weapons to a single recycle bin.

A simulated magazine useful to provide for simulated firing of a firearm includes a cycling lever arm which is depressed once every time the firearm is cycled; a linearly shaped counting plunger; a plunger spring biasing the plunger in an upward position; and a spring assembly connected to the cycling lever arm and acting upon the plunger. Depression of the cycling lever arm causes the plunger to move incrementally upward. When the plunger is in a fully up state, a slide catch trigger extends upward from the magazine, the slide catch trigger causing a slide of the firearm to remain in a back, open state.

An extraction system for removing an object from a bore, the extraction system comprising an extraction pole assembly comprising a plurality of extraction poles, each extraction pole having a proximal end and a distal end; and a plurality of centering couplers, each centering coupler of the plurality of centering couplers comprising a partial spherical outer surface sized to complement a diameter of the bore, a proximal end configured to couple to a distal end of an extraction pole, and a distal end configured to couple to a proximal end of the extraction pole. The extraction pole assembly can be operable with a press assembly comprising a clamp configured to secure to the structure having the bore, and an extendable member configured to provide an input force to an extraction pole of the extraction pole assembly.

The present invention proposed a method to achieve the caseless ammunition firing with liquid propellant for automatic weapons. The weapons with this method were driven by a servo motor that led a slider (9) for linear reciprocating motion, and then the slider (9) drove a combustion chamber (3) and a rotary lock (4) to complete the projectile loading and the combustion chamber (3) locking. The combustion chamber (3) locking was done with the help of a fixed plunger (7).

A separated binary liquid gunpowder was used as a propellant. The constant liquid propellant injection pressure was maintained by a constant pressure regulator; and an electronic fire control unit (EFCU) precisely control two solenoid valves opening time in order to control the injection amount of the mixture. The gunpowder was injected through the nozzle on the plunger (7), and was ignited by an electronic igniter to launch the projectile.
