US12624910 - Reduced weapon system blowback

A reloading firearm featuring a mechanism to reduce the blowback of toxic propellant gasses towards the warfighter. The reloading assembly acts in plural segments to increase the firing chamber-closed dwell time, while limiting adverse impact to the overall nominal rate of fire. Greater dwell time corresponds with reduced exposure of the warfighter to propellant gasses. Moreover, increasing the dwell time without otherwise altering the firing cycle has the additional effect of delaying the breech opening after the cartridge is fired. This delay in breech opening permits gas pressure at the muzzle, which may be elevated and/or constrained by flash and/or sound suppression, to dissipate before the breech is opened. Accordingly, when the breech opens later in the firing cycle, there is a reduced pressure gradient across the combination of barrel and firing chamber, which reduces a driving force of propellant gasses towards the warfighter via the open breech.

The plunger comprises an inclined camming surface which slideably engages a mating inclined camming ramp on the lever. Wedging action applied to the bolt catch lever by the plunger rotates the lever about its pivot axis to disengage and release the bolt.

US12595983 - Diverging central bore for firearm sound suppressor

An apparatus and methods are provided for a front plate having a diverging central bore for firearm sound suppressors that improves noise and flash characteristics during firing a weapon. The central bore is disposed between a back surface and a front surface of the front plate. An untapered portion of the central bore extends from the back surface to a diverging portion that opens toward the front surface. The diverging portion includes a curvature profile configured to allow for more controlled expansion of high-pressure propellant gases exiting of the suppressor through the central bore. The curvature profile provides an included angle of the central bore that decreases secondary flash events accompanying the expulsion of propellant gases accompanying a fired bullet exiting the suppressor through the central bore. The curvature profile exhibits a cross-sectional area of the central bore that is proportional to a distance along the diverging portion.

US12595984 - Gun muzzle sound suppressor

A gun muzzle sound suppressor including a plurality of segments, wherein each segment among the plurality of segments including a cylindrical housing having an inner surface and an outer surface, wherein the each segment further includes a conical baffle fixedly attached to the inner surface of the each segment's cylindrical housing, wherein the each segment further includes a plurality of vanes fixedly attached to the outer surface of the each segment's cylindrical housing; an outer housing having an inner surface, wherein the outer housing is fitted for sliding receipts of the segments, wherein upon the receipts of the segments, the vanes contact the outer housing's inner surface; and a pair of rings fixedly attached to the outer housing, one the rings among the pair of rings being positioned muzzlewardly from a muzzleward-most segment among the plurality of segments, the other ring among the plurality of rings being positioned breachwardly from a breachward-most segment among the plurality of segments.

US12595985 - Customer-serviceable forearm assembly

A firearm forearm assembly is provided. Generally included is a forearm retainer that is a flexible component installed in the forearm, which is then momentarily deflected to admit each action bar. Once the forearm assembly is installed in the firearm, the firearm's magazine tube is introduced and prevents further deflection of the retainer, thus locking the forearm assembly together during use. As a result, the forearm assembly is easily disassembled by the user without the use of tools by deflection of the retainer and removal of the action bars. But at the same time, the integrity of the firearm is preserved during operation.
