Abstract: An arm brace apparatus for use with a firearm allows for a reduced form factor when the arm brace is not needed by the shooter. The arm brace apparatus includes a hinge which allows for a substantial portion of the brace to pivot between an open or deployed configuration, a useful position when shooting, and a closed or stowed position, useful for transportation or storage of the firearm to which the arm brace is attached. A latch mechanism allows the device to be locked in either the open or closed position.

Abstract: An assembly for mounting a handguard to a firearm utilizes a biasing element disposed intermediate the barrel nut and the interior end of the handguard and a clamping element also disposed intermediate the barrel nut and the interior end of the handguard but positioned opposite the biasing element about the perimeter of the barrel nut. One or both of the biasing element and clamping element have multiple surfaces which mimic portions of the exterior profile of the barrel nut to prevent any of longitudinal, axial, or radial misalignment of the handguard relative to the axis of the firearm barrel.

Abstract: An assembly for mounting a handguard to a firearm prevents longitudinal, axial, or radial misalignment relative to the axis of the firearm barrel by utilizing a biasing element disposed intermediate the barrel nut and the interior diameter of the handguard, a clamping element positioned opposite the biasing element about the perimeter of the barrel nut and having a first wedged surface, and a threaded wedge configured to co-act with the first wedged surface of the clamping element to directionally force the clamping element against the barrel nut in a manner that prevents canting of the handguard.

Abstract: An assembly for mounting a handguard to a firearm utilizes a clamping element disposed intermediate the barrel nut and the interior end of the handguard. The clamping element has multiple surfaces which mimic different diameter portions of the exterior profile of the barrel nut to prevent any of longitudinal, axial, or radial misalignment of the handguard relative to the axis of the firearm barrel. The clamping element may be secured in place with multiple fasteners having the same or different axes of movement.

Abstract: The present invention includes a novel method to fabricate corner cube retroreflectors, CCRs, where a majority of the wafer area acts as CCRs as compared to a maximum of 33% in previous MEMS CCRs. The present invention also allows for the fabrication of moveable cantilevers which operate at one-third the voltage as compared to a conventional planar cantilever.

Abstract: A modular fore-end rail assembly for mounting onto a firearm includes an upper hand guard, a lower hand guard and a clamping member that combines with the rear portion of the upper hand guard to encircle and clamp onto the barrel nut thereby supporting the entire assembly from the front of the upper receiver and preventing any transfer of load into the barrel. The lower portion of the hand guard is slidably received into channels formed in the upper hand guard and is retained in its installed position by a spring biased detent located in the clamping member. The lower hand guard is removable by simply depressing the detent and sliding the lower hand guard forward. By providing for the easy removal of the lower hand guard, other auxiliary devices may be mounted to the upper hand guard.
