The trigger assembly having a housing with an adjustment means in the form of a fastener in communication with one or more trigger springs that interface with a trigger. The adjustment means can be configured to adjust a length of one or more trigger springs to adjust the trigger pull force of the trigger assembly. A calibrated force tester can be coupled to a portion of the trigger to test the amount of trigger pull force necessary to release a hammer of the trigger assembly. The trigger assembly enables a calibrated repeatable method of giving a user the ability to adjust the trigger system pull force by the means of a calibrated laser etched scale on the trigger housing that works in conjunction with the adjustment means.

US12435942 - Suppressor for a firearm

A suppressor for a firearm has a body defining an internal volume, a baffle in the body and defining a baffle aperture on a bore axis, a piston element including a mount facility configured for connection to the barrel, the piston element defining a piston bore registered with the bore axis, and the piston element operable to reciprocate with respect to the body along the bore axis between a rest position in which the piston element contacts the baffle and a recoil position in which the piston element is away from the baffle. There may be a spring interfacing the piston element and the body and be operable to bias the piston element to the rest position. There may be a second spring operable to interface the body and the piston element only when the piston element is in a range of positions proximate the recoil position.

US12435943 - Bullpup-type gun with barrel positioned at bottom

The present invention relates to a bullpup-type gun with a barrel positioned at the bottom, in which the bullpup-type gun basically has a bullpup-type shape, and a barrel, a loading handle, and a shell discharge part are provided at a lower side of a body part, which may prevent burns and injuries to a user caused by a configuration in which a shell is discharged upward, and a height difference between a front sight and a rear sight may solve a problem with an aiming degree caused by a configuration in which the barrel is disposed at the bottom.

US12435944 - Tubular archery bow riser

An archery bow is provided including opposing limbs and a riser. The riser can include a riser handle and one or more primary riser elongated elements extending away from the handle to respective limbs. The primary riser elongated elements can be straight, elongated round or other shaped tubes, rods or bars constructed optionally from a composite or other material. Vents can be included in ports of the riser to facilitate escape of air when riser elongated elements are installed in those ports. The riser can include one or more connector lugs disposed between tube portions to facilitate attachment of accessories to the elongated elements. The elongated elements can be bonded, adhered or otherwise fixed to the riser handle, struts, lugs and/or limb pockets, which can be constructed from a metal such as aluminum, titanium or an alloy, and which can handle significant moments and forces transferred via the elongated elements.
