20150323274 | FRAME ASSEMBLY FOR STRIKER-FIRED PISTOL - A frame assembly for facilitating disassembly of a striker-fired pistol is disclosed. The frame assembly facilitates removal of the slide from a striker-fired pistol without trigger manipulation and with minimized potential for a round to be chambered. The frame assembly includes a takedown safety lever and a takedown actuation lever. Movement of the takedown safety lever causes the sear to be moved such that subsequent slide motion will not result in the storage of striker energy. Movement of the takedown safety lever is only possible while the slide is refracted beyond the point at which a chambered round would be ejected. Removal of the slide does not require pulling the trigger. The positioning of the takedown safety lever motion for disassembly may be precluded by the presence of a magazine in the gun, thereby eliminating the possibility that a round could be chambered during subsequent slide motion. | 11-12-2015 |
20150308799 | HOLLOW POINT BULLET AND METHOD OF MANUFACTURING SAME - Hollow point bullets and methods of manufacturing such bullets are herein disclosed.

The cavity formed in the core may have a cross-section shape defined by a plurality of points spaced equidistantly about the circumference of an imaginary circle. A plurality of stress risers may be formed in the core, each stress riser extending from the cavity to a v-shaped channel in coincidence with a point of the cross-section shape of the cavity. | 10-29-2015 |
20150276335 | UPPER RECEIVER WEAR SURFACE - A firearm receiver wear surface is disclosed. When inserted within a corresponding wear surface cavity in a firearm receiver, a wear surface pin contacts and engages with the hook of a charging handle latch. In one example, a wear surface cavity for receiving a wear surface pin may be machined within the upper receiver of a modular rifle. The positioning of the wear surface cavity and wear surface pin can prevent the charging handle latch from contacting and causing unwanted wear on the upper receiver. In some embodiments, the wear surface pin may be a replaceable pin-shaped object made from a more durable material than the material of the upper receiver. For example, the wear surface pin may be a steel coiled spring pin that is pressure-fit into a wear surface cavity in an aluminum alloy upper receiver. | 10-01-2015 |
20150267985 | SEAR TRIP BAR FOR A FIREARM - A sear trip bar for use in an automatic firearm is disclosed. In accordance with some embodiments, the sear trip bar can be operatively interfaced with the bolt carrier and the automatic sear of the host firearm. The disclosed sear trip bar can be configured such that, upon sufficient displacement thereof (e.g., exhaustion of its stroke length) by the bolt carrier, the automatic sear may be caused to trip. Thus, the disclosed sear trip bar can be utilized, for example, to transfer the force of the moving bolt carrier during a given firing cycle to automatically trip the sear so as to initiate one or more subsequent firing cycles without having to release and again operate the trigger of the host firearm. The disclosed sear trip bar can be utilized, for example, in pistol-caliber and/or rifle-caliber automatic firearms. | 09-24-2015 |
