Abstract: A precision ammunition cartridge reaming device employs a body die having an interior cavity into which an ammunition cartridge is insertable through a first end. A reaming tool rotationally powered is insertable into the interior cavity through a second end. Rotation of the reaming tool trims the interior of a neck area of the ammunition to form a concentric surface with the exterior thereof. The distal edge of the cartridge may also be trimmed by the reaming tool to form each sequentially inserted cartridge to an equal length.

Abstract: A trigger assembly apparatus includes spherical portion(s) and spherical bearing(s), rounded sear, stabilizing catch, and complimentary shield. In an exemplary embodiment, the spherical portion(s) and spherical bearing(s) respond to non-linear movement. Further, the interaction of the spherical portion(s) and spherical bearing(s) results in the mobility of the trigger in relation to the 6 degrees of freedom thereby resulting in the firearm being generally unaffected by side to side movement of the trigger during activation. The trigger assembly may also include but is not limited to a rounded sear, stabilizing catch, and complimentary shield. The rounded portion of the sear engages the hammer stop notch at a single point further resulting in the firearm being generally unaffected by side to side movement of the trigger. Additionally the stabilizing catch and shield helps facilitate the proper reset of the trigger assembly.

Abstract: A firearm with a compound lever trigger mechanism includes a first member pivotally attached to a firearm receiver at a first pivot and a first lever arm extending away from the first pivot attachment point to a sear. The first member is pivotable between a first position where the sear engages a firing element and a second position where the sear does not engage the firing element. A trigger member is pivotally attached to the first member first lever arm with a trigger blade arm extending away from the second pivot in one direction and a bearing arm extending away in another direction toward bearing contact with a surface of the receiver. Pulling the trigger blade arm causes the trigger member to pivot relative to the first member and the bearing arm to move in bearing contact against the receiver, thereby pivoting the lever arm from the first position to the second position.
