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 visual indicator is not visible beyond the bottom of the magazine when the spring has exceeded its compressive set tolerance.

US12624914 - Weapon usage monitoring system having predictive maintenance and performance metrics

A method for initiating a responsive action based on an operational status event of a firearm is provided. The method can include receiving, by an event detection module, acceleration and rotation input signals from an inertial measurement unit configured on the firearm. An occurrence of an operational status event based on the acceleration and rotation input signals are identified by the event detection module. A tipping signal is generated by the event detection module based on the identified operational status event. The tipping signal is received at a responsive infrastructure. The responsive infrastructure performs a responsive action based on the tipping signal.

US12624915 - Suppression device with purposely induced porosity for firearm

A suppression device includes a body including an outermost external surface of the suppression device, a first end, and a second end; a core configured to be inserted into the body and including a baffle; and a bore extending completely through and along a longitudinal axis of the suppression device, wherein porosity is a fraction of a volume of pores per volume of mass in a material of the suppression device, a structure of the pores is not random, and the porosity of a portion of the core including the baffle is different than the porosity of a portion of the body.

US12624916 - Dry fire device using sound detection

A dry fire device includes a housing, and a weapon-usage activation assembly, which includes a microphone, a controller and a memory. The microphone is configured to sense a sound during use of the dry fire device, and the controller is configured to extract amplitude and frequency data of the sound and compare it to a range of values stored in the memory. If the sensed sound is in the range, the controller is configured to command the weapon-usage activation assembly to initiate a weapon-usage activity, and if not in the range, no weapon-usage activity is initiated.

US12624917 - Hybrid stabilizer rod

A hybrid stabilizer rod preferably includes a stabilizer tube, a first end cap and a second end cap. The stabilizer tube preferably includes a base tube, a first carbon fiber sheet and a second carbon fiber sheet. The first carbon fiber sheet includes a plurality of parallel fibers. The second carbon fiber sheet includes a plurality of first and second fibers. The first carbon fiber sheet is wrapped around the base tube. The second carbon fiber sheet is wrapped around the first carbon fiber sheet. The first and second end caps preferably include a thin head formed on a first end of a cap body and a tapered bore formed in a second end of the cap body. A threaded tap is formed in the first end of the cap body. An outer perimeter of cap body is sized to be received by an inner perimeter of the base tube.
