Abstract: Trigger guard assemblies for firearms include a trigger guard movable between a closed positon; and an open position providing greater access to a trigger bow of the firearm. The trigger guard assemblies also include a post that engages the trigger guard, and is movable in relation to the trigger guard between a retracted position and an extended position. When in the retracted position, the post does not interfere with movement of the trigger guard between the open and closed positions. When in the extended position, the post interferes with movement of the trigger guard between the open and closed positions, and exerts a lateral force on the firearm to further secure the trigger guard to the firearm.

Abstract: The present disclosure generally relates to a bolt catch device that prevents the bolt of a bolt carrier assembly of a firearm from moving to its forward position so as to prevent the firearm from being discharged until the user manually moves the bolt catch. The bolt catch is mechanically coupled to the selector of the firearm via a linkage, so that the bolt catch can be moved by way of the selector. This feature can prevent a self-loading firearm that otherwise could function on a semi-automatic basis from operating in such a manner.

Abstract: The disclosure relates to an adjustable firearm sling that allows a user to rapidly adjust orientation of the firearm between resting and firing positions.

Abstract: Gas tube assembles are provided for mounting on a gas block of a gas-actuated firearm having an internal passage configured to receive propellant gas from a barrel of the firearm. The gas tube assemblies have a gas tube that defines a passage extending between a forward and a rearward end of the gas tube. The gas tube assemblies also have a mating portion secured to the gas tube. The mating portion has a flange that can be secured to the gas block so that the flange prevents linear and rotational movement of the gas tube in relation to the gas block.

Abstract: Linear trigger mechanisms for firearms include a trigger slide mounted on, and configured to move linearly in relation to a chassis; and a hammer. The trigger slide has a rolling element, such as a pin-mounted roller or a rolling pin, that engages a contact surface on the hammer and thereby restrains the hammer against its spring bias. When the user pulls the trigger to discharge the firearm, the trigger slide moves linearly, causing the rolling element to roll off of the contact surface and thereby release the hammer. The trigger mechanisms can be equipped with a drop safety that rotates in response to an impact between the firearm and the ground, so as to interfere with the movement of the trigger slide and prevent the release of the hammer.

Abstract: The disclosure relates to a foldable iron sight assembly for a firearm that includes a rail mount including a base, a clamp, a rail pin, and a base locking portion; a windage or elevation sight member that includes a sight member locking portion rotatably connected to the base locking portion, wherein the base locking portion and the sight member locking portion are configured to interlock with each other; and a locking mechanism that includes an axle and a biasing element, wherein the sight member is rotatable between a locked raised position and a locked lowered position when a force applied to the sight member compresses the biasing element. Also disclosed is a firearm having a rail to which the assembly is secured, and a method of operating the assembly.

Abstract: The disclosure relates to an adjustable rear iron sight for a firearm. The rear iron sight includes features that maintain its various components in a state of alignment, that permit the rear iron sight to be locked in raised and lowered positions, and that bias a dual aiming aperture against movement while nevertheless permitting the user to easily rotate the dual aiming aperture to switch between its large-diameter and small-diameter apertures.
