US12631414 - Gun magazine including spring with uneven stack height upon compression

A gun magazine spring and magazine assembly having a novel design. The coils of the spring are configured to nest in certain regions and overlap in others. The result is that—as the spring nears its fully compressed state—the spring has an uneven stack height from left to right. The uneven stack height produces a predictable lateral displacement of the follower. The higher of the two stacked sides of the spring protrudes laterally outward through a lateral relief in the follower. This feature allows the spring and follower to overlap in the vertical direction to a greater extent than would be possible with conventional laterally-even spring nesting. The additional overlap produces additional internal space while also ensuring that the spring and follower assembly behave in a predictable manner.

US12631415 - 3D-printed support structures for sound suppressors

The supports further define channels between the baffles and the wall, decreasing weight without sacrificing structural strength. The channels are open or sealed to facilitate flow of pressurized gas between chambers defined by the baffles and the wall, the pressurized gas being generated during discharge of the firearm. The pressurized gas decompresses and cools while traveling between the chambers and the channels, thereafter exiting the sound suppressor at a decreased pressure, temperature, and velocity, which may attenuate a noise associated with the discharge.

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.

US12607431 - Structures for firearms

A buffer tube for a firearm can include a body defining an interior cavity for receiving a buffer spring and a rail disposed on and/or formed from the outer surface of the body. The rail can include one or more pin holes configured to receive a pin of a stock to lock the stock in a position. The buffer tube can also include a slide bar channel defined through at least a portion of the rail and configured to allow a slide bar to slide therein relative to the one or more pin holes to urge a pin out of a respective pin hole and/or to block a pin from being received by the pin holes.

US12607433 - Method, apparatus, terminal, and storage medium for image processing

A method and device for image processing, a terminal and a storage medium. The method includes acquiring an image generated by an infrared sighting telescope arranged on a firearm; determining a grey level dynamic range of a preset first portion of the image; if a difference value between the grey level dynamic range value and the grey level of the preset second portion reaches a preset starting processing threshold, performing mean filtering processing on each pixel of the preset second portion to obtain a filtered grey level; and if the filtered grey level is greater than a preset grey level expectation threshold, processing the pixel, so that the grey level of the pixel is close to the grey level expectation value.

US12607438 - Projectile and firearm system

A cartridge is disclosed with a casing and a projectile, wherein external ballistic stability is provided by a center of pressure of the projectile being rearward of a center of mass of the projectile. The projectile includes flight control surfaces that cooperate with the bore of a barrel without requiring rifling or sabots. The projectile can include fin configurations that cooperate with the bore to form a bearing surface with the bore.

US12601554 - Firearm loader

A firearm loader includes a body defining a cavity with a first open end and a slot communicating with the cavity and an interface arm extending from the body. A method includes positioning a firearm loader on a firearm, the firearm loader comprising a body defining a cavity with a first open end and a slot communicating with the cavity and an interface arm extending from the body and transferring cartridges positioned in the cavity through a magazine opening of the firearm by engaging the cartridges through the slot and pushing the cartridges through the first open end.
