In response to application of a force to the trigger lever, the lower trigger body may rotate and cause the trigger tower to rotate to release the trigger tower hook from the hammer sear hook.

US12698944 - Thermoacoustic heat exchanger suppressor

A silencer core for suppressing and dissipating at least one of a sound, a flame, or a quantity of heat of a projectile fired from a firearm includes a thermoacoustic organic structure (TOS) extending along a central axis from a first end to a second end. The TOS defines a central bore extending along the central axis from the first end to the second end. The central bore enabling the projectile to pass through the TOS when fired from the firearm. The TOS also defines a network of interconnected passages or a mesh configured to move at least one of combustion gases, heat, or sound from the central bore to an outside diameter of the TOS. The TOS has a density between 1.5 g/cm 3 to 4 g/cm 3 .

US12698946 - Adjustable firearm stock with passive tensioning mechanism

Embodiments of the disclosure relate to adjustable stocks for firearms and methods for installing an independently sprung tensioning mechanism. The adjustable stock comprises a stock body attached to a buffer tube, with a lever-operated tensioning mechanism. The mechanism includes a tensioning block with fins to grip the buffer tube, an indexing pin, and a retaining pin. When the lever is depressed, the tensioning block and indexing pin disengage, allowing longitudinal adjustment of the stock on the buffer tube. The tensioning block applies upward pressure on the tube, compensating for rotational tolerances during assembly. Both the tensioning block and indexing pin move independently when engaging with the buffer tube but move together when disengaging. The indexing pin is biased towards the buffer tube by a spring, while another spring biases the tensioning block. The lever engages the retaining pin to retract both the indexing pin and tensioning block.

US12698948 - Aiming device for firearm

An aiming device for a firearm comprising a housing and a near infrared illuminator. The near infrared illuminator is positioned in the housing and is configured to output near infrared light with adjustable beam divergence to provide a field of illumination that is adjustable. The near infrared illuminator includes a divergence adjustment input positioned on an upper side of the housing that is movable by a user to adjust the beam divergence.

US12698951 - Method for determining position of a laser point applied in a firearm training simulation system using infrared lasers

A method to detect, identify and determine the position of laser points from infrared laser emitters in a firearm training simulation system. The method consists of two steps. This first step combines some common tools such as a camera with a filter switcher and edge and corner detecting algorithms in image processing to provide a fast automatic screen calibrating method. The second step is to detect laser point objects in each frame continuously captured by the camera, and then further process these objects to identify laser shots, filter out noisy objects, and eventually detect simulated shots from different laser emitters and determine the final mapped position of the shot.
