A breech for a pistol including a barrel, which includes at least one barrel block and one chamber, as well as a slide and a breech guide, which is designed to move on a guide rail of a frame of the pistol and on which a socket having a breech face is formed. In order to increase the mechanical stability, the barrel block includes at least one recess on each side, which interacts with centering rails that are provided on the inside of the breech guide and are formed to be complementary to the recesses in terms of form and function.

Systems for attaching a bottom metal to a rifle action. The systems include adjustable pillars disposed within a rifle chassis that may be adjusted in length to accommodate different bottom metal geometries, rifle chassis geometries, and/or different rifle action geometries.

A feed tray assembly for a belt-fed weapon includes a bottom tray portion configured for mounting at a top of the weapon. The feed tray assembly further includes a feed tray cover mounted to the bottom tray portion and configured for lateral sliding opening and closing movement, such as on laterally extending pins riding in corresponding channels of the bottom tray portion. The feed tray cover has (1) a closed position in which it covers the bottom tray portion to retain the belt of ammunition during operation, and (2) an open position laterally displaced from the closed position to enable insertion of the belt of ammunition. Due to this lateral sliding movement of the feed tray cover, a sighting optic may be mounted on the weapon with a forward portion directly above the feed tray assembly without any undesired mechanical interference.

An apparatus for ambidextrous control of a bolt carrier and/or a magazine release is disclosed. In certain examples, the apparatus includes a lower receiver of a firearm including a protrusion extending outward from a first side of the lower receiver, the protrusion. The protrusion, in certain examples, includes a first slot for receiving an L-shaped lever, the L-shaped lever having a vertical arm coupled to a bolt catch lever and a horizontal arm that extends through a trigger area to a second side of the lower receiver that is opposite the first side. In certain examples, the protrusion also includes a second slot for receiving a magazine catch lever.

A metallic component of a lower receiver for a firearm is disclosed herein. The metallic component includes a body with apertures between a first side of the body and a second side of the body. The body can be configured to mate with another component of the lower receiver along the second side. The two lower receiver components can be detachably affixed together via the apertures. The body can have a ring-shaped protrusion at a first end. The ring-shaped protrusion can extend outward perpendicular to the first side and the second side.
