Abstract: A collapsible ballistic shield which provides a degree of protection against ballistic threats. The shield includes a head plate, an upper torso plate, a lower torso plate, an upper lock-and-release hinge joint, a lower lock-and-release hinge joint, a primary handle, and a strap-mounting fastener. The head plate is positioned opposite to the lower torso plate, across the upper torso plate to outline a shape of a body. The head plate is pivotably attached to the upper torso plate by the upper lock-and-release hinge joint. The lower torso plate is pivotably attached to the upper torso plate by the lower lock-and-release hinge joint. Resultantly, the shield may be collapsed, expanded, and broken down. The primary handle provides a grasping point and is mounted to a rear surface of the upper torso plate. The strap-mounting fastener allows the user to attach the shield to external structures.

Abstract: A firearm accessory mount is an apparatus that maximizes the mounting surfaces on a firearm while allowing the interchangeability of a barrel onto and off of the firearm. The apparatus includes a left tactical rail, a right tactical rail, a gas-cylinder clamp, an upper tactical rail, and an elongated fixture with a transversal arc-shaped cross section. The left tactical rail, the right tactical rail, and the upper tactical rail allows for a variety of firearm accessories to mount onto the apparatus. The gas-cylinder clamp attaches the apparatus onto the gas cylinder. The elongated fixture braces the barrel while attached to the firearm. The arc-shaped cross-section of the elongated fixture allows the barrel to be replaced or a new barrel to be attached without altering the position and orientation of the firearm. The apparatus further includes a lower tactical rail that allows the mounting of firearm accessories beneath the gas cylinder.
