A charging handle is disclosed. The charging handle may include an elongated body having a forward end and a rear end, a handle assembly disposed about the rear end of the elongated body, and a latch assembly disposed about the rear end of the elongated body in mechanical communication with the handle assembly. The charging handle may include an ambidextrous latch and/or interchangeable handles.

The present disclosure describes a foldable firearm that collapses into a folded state under spring pressure. The foldable firearm may include a foldable grip assembly. The foldable grip assembly may include a foldable pistol grip, a foldable trigger assembly, a folding bar, and a foldable hand stop. The foldable grip assembly may fold into the top shell of the foldable firearm. The foldable firearm may also include an ambidextrous charging handle assembly that may include a bottom portion, a top portion, a guide bar, and two opposing charging handles. The charging handles may be pulled to unfold the foldable firearm, and/or butterflied such that pivoting one charging handle causes the other charging handle to pivot. The first-pivoted charging handle may then be pulled rearwards to unfold the firearm. The first-pivoted charging handle may then be pulled further rearwards to rack the slide of the foldable firearm.

A lower receiver that may be right hand or left hand configurable is provided. The lower receiver includes a static ejector that can be easily configured for right hand or left hand positions within the same lower receiver and a magazine button assembly having a left magazine button and a right magazine button that are operatively coupled together so that either magazine button can be pushed to release the magazine. This allows the gun builder to use this one lower receiver to build a right or left handed rifle.

A firearm includes an integrated rail and sight system that slidably mounts to the top of the firearm and is also retractable and detachable from the firearm. The rail may slide on and off the top of the firearm and may include integrated front and rear flip down sights. Both sights are pinned to the rail and can fold down to the rail such that they are flush with or seat below the top portion of the rail. This permits accessories to be mounted to the rail without the sights interfering with the mounting of the accessories or without the sights interfering with the operation of the accessories. The firearm further includes an ambidextrous charging handle mounted through the integrated rail and sight system.

a slideable ejection port cover having at least two configurations, an open configuration in which shell ejection via the ejection port is enabled, and a closed configuration in which the ejection port is substantially immovably covered; the ejection port cover comprising a shutter operatively connected to a locking component, the shutter slideable along a longitudinal axis of the receiver; wherein the locking component comprises a spring configured, at such times as the ejection port cover is in the closed configuration, to hold the locking component in a pressure-applying mode against the receiver, the pressure-applying mode being a default mode, thereby immobilizing the shutter relative to the receiver, and the locking component configured to compress the spring when pulled manually away from the receiver, thereby enabling reversible transformation of the ejection port cover from the closed configuration to the open configuration.
