Abstract: A device and method to accelerate solid metal slugs to high speeds. In one embodiment, a large electric current is passed through an outer cylindrical metal tube enclosing in part a metal slug, a central electrode, and a conducting tail coupled at opposite ends to the. metal slug and the central electrode. Electromagnetic forces accelerate the metal slug to a point high enough to mechanically separate the conducting tail. On separation, a plasma is generated by the passage of electric current though a gas produced by vaporization of the conducting tail and nearby materials. An insulator enclosed within the tube prevents the plasma from shorting to the outer tube until the current flow has produced a sufficient magnetic field to contain the plasma. The metal slug is then accelerated to high speed by a combination of electromagnetic forces and mechanical pressure from the hot gas through which the electric current is passing.

Abstract: A fixture for use with AR15/M16 type firearms is provided herein.

Abstract: An ambidextrously operated bolt catch assembly for a firearm facilitates ease of use by either right handed or left handed shooters. The ambidextrous bolt catch assembly includes two levers, one on each side of the firearm, that interact with each other. Each lever has a primary contact surface and a secondary contact surface. By depressing the primary contact surface of either lever, both levers rotate to move the bolt catch assembly from a displaced position to a static position. Conversely, by depressing the secondary contact surface of either lever, both levers rotate to move the bolt catch assembly from a static position to a displaced position.
