20150089854 | Pump Action Rifle and Action Lock Mechanism - An action lock for a Modern Sporting Rifle pump action firearm is pivotably mounted within the lower receiver of the rifle and has a stop surface that engages a contact surface on the bolt carrier when the bolt carrier is in battery. A cam on the hammer or the trigger engages a cam surface on the action lock when the hammer is released by a pull of the trigger. Cam action rotates the action lock out of engagement with the bolt carrier, unlocking it and allowing the fore end grip to be pumped to cycle the action and extract and eject the spent casing and strip and chamber a new round. | 04-02-2015 |
20140259846 | Firearm with Ambidextrous Safety - A firearm has ambidextrously actuatable safety levers with the connection between the levers being effected within the frame and offset from the frame centerline to mitigate lost motion between the levers and prevent yielding of the shaft connecting them. The levers have raised surface portions which are hidden behind a plate. The raised surface portions contact the frame and, because they are hidden behind the plate, leave no visible marks on the finish due to rotation of the levers. | 09-18-2014 |
20140215880 | Firearm Having Magazine Safety and Take-Down Mechanism - A firearm has a magazine safety and a take-down mechanism. The magazine safety operates in conjunction with a trigger bar and a disconnect bar. The magazine safety has a safety arm which moves the disconnect bar out of engagement with the trigger bar when a magazine is inserted. This permits the trigger bar to engage the sear. When the magazine is removed, the safety arm disengages from the disconnect bar, permitting the disconnect bar to move the trigger bar into a position where it cannot engage the sear. The safety bar also operates as a take-down mechanism. When moved to a take-down position, the safety arm engages and moves the sear into a position where it cannot engage the striker so as to permit removal of the slide carrying the striker from the firearm. | 08-07-2014 |
20140196339 | Extractor for Self-Loading Firearm - An extractor for a self-loading firearm is mountable on a breech block and is formed of a body having a hook at one end.

20130074391 | DROP SAFETY FOR A FIRING PIN OF A FIREARM - A firearm has a firing mechanism that includes a firing pin, a drop safety, a spring mounted to the drop safety and a trigger in mechanical communication with the firing pin and the drop safety. The drop safety includes a roller portion having an outer circumferential surface and an inner opposing wall. When the trigger is actuated, the opposing wall of the drop safety abuts and engages the firing pin in the forward-most axial position thereof, thereby allowing the firing pin to strike a primer of a chambered round of ammunition. In all other configurations, the spring rotationally biases the drop safety so that the outer circumferential surface of the roller portion of the drop safety blocks the forward axial reciprocation of the firing pin, preventing the firing pin from engaging the primer of a chambered round of ammunition. | 03-28-2013 |
