| 170 | Firearm receiver with extended bridge | US12208065 | 2008-09-10 | US08176833B2 | 2012-05-15 | Tomas Quis |
| A firearm receiver with an extended bridge is created to prevent the fully automatic fire of an assault rifle. The extended bridge receiver has a narrowed magazine well for a single stack removable magazine, safety catch with one or more grooves on its lower left hand side, new sporting stock where grip part and butt-stock part form one unit and barrel extension permanently attached to the muzzle. The receiver can be configured with a rivet on the bridge in a location that prevents backward turning of the safety catch, where the modified safety catch has two positions (i.e. safe and fire), rather than the three positions consistent with a fully automatic firearm. In a second version, the extended bridge lacks a release lever groove. In yet another version, an inseparable, double stack magazine box is used. | ||||||

The elongated body defining a second aperture. The second aperture being defined through a portion of the elongated body to enable a tension element, positioned at least partially within the second aperture, to be urged from the elongated by via an interaction with the tension member. The fastener is insertable into aligned apertures of respective first and second weapon components. The tension element being urged from the elongated body to interact with the second weapon component to urge the second weapon component into further engagement with the first weapon component. | ||||||
| 173 | Firearm selector removal and installation tool | US12759821 | 2010-04-14 | US08069606B1 | 2011-12-06 | Thomas W. Saur |
| This tool makes it possible to more conveniently handle the “selector” element on a conventional M16/M4 family weapon when the selector must be removed or reinserted. As will be appreciated by those in the gun repair trade, in the disassembly or reassembly of such weapons the handling of the selector element is a tricky and painstaking activity. This disclosed tool handily is an assist in such activities. The tool is inserted in the opening in the receiver of the selector element and rotated. An offset circular cam means on the tool when rotated will handily depress the detent element (which necessarily must be done and it also has a spring beneath it). A bumper end cap at the distal end of the tool will carefully engage the selector element to gently push on it if needed (or in the reverse operation for the tool to be gently backed away there from as the selector is repositioned into the weapon). A longitudinal groove on the cam means will signal to the user when the proper rotation has been achieved to adequately depress said detent element. | ||||||
| 174 | LOCKABLE SAFETY FOR STRIKER-FIRED FIREARM | US11881096 | 2007-07-25 | US20110219656A1 | 2011-09-15 | James McGarry |
| A striker-fired firearm with lockable manual safety and method of use. The firearm in one embodiment includes a frame, a chamber for receiving a cartridge, a striker movable to strike the cartridge, a trigger movably mounted to the frame, a trigger bar coupled to the trigger and operable to engage and release the striker to discharge the firearm, a manually-operated safety adapted to engage the trigger bar and selectively movable between a first deactivated position and a second activated position wherein the safety engages the trigger bar to prevent release of the striker, and a cylindrical locking member rotationally disposed in the frame. In one embodiment, the locking member, which may be a lock pin in some embodiments, includes a blocking surface that is engageable with the safety. The blocking surface is rotatable to a blocking position wherein the safety cannot be moved from the second activated position to the first deactivated position by a user. In one embodiment, the blocking surface projects into a slot and engages a protrusion on the safety to block the movement of the safety. Preferably, the locking member is key-operated. | ||||||
