摘要： A safety selector for a firearm, including a first lever including an integrally formed safety shaft and a first handle located outside the lower receiver for actuation, as well as a bearing portion, a selector portion and a connecting portion. To facilitate disassembly and interchangeability, the first lever is configured for spring-biased coupling to a securing element and has, on the connecting portion, a positioning protrusion projecting toward the opposite side of the weapon. In a longitudinal direction, the positioning protrusion has a shape-complementary bore for receiving a connecting assembly which includes a connecting element, a spring and a spring lock.

摘要： A device implementable on a firearm includes a monolithic upper receiver, comprising an upper receiver portion and a handguard portion, which is configured to accommodate non-proprietary barrel assemblies dimensioned according to United States military standard (mil-spec) barrel assembly dimensions and non-proprietary bolt carrier groups (BCGs) dimensioned according to mil-spec BCG dimensions. The device also includes a charging handle assembly configured to be coupled to an operating rod of a gas system of the firearm and forward of a BCG of the firearm. The device further includes a barrel locking system including a locking plate and a locking screw. When the locking screw is screwed into a threaded hole on the locking plate, the locking plate engages with a side of a barrel extension of the barrel assembly in a radial directions perpendicular to a longitudinal axis of the barrel assembly.

摘要： 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.

摘要： 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.

摘要： A universal chassis for a firearm includes sidewalls. The sidewalls define a trigger well that is configured to receive a trigger mechanism. One of the sidewalls may define a cutout adjacent the trigger well. The chassis is configured to interchangeably receive a bolt action and a barrel for a shotgun, a muzzle loader, and a rifle. The cutout is sized and dimensioned to receive a lever arm of the bolt action.

摘要： A novel and improved rotating stock butt and rotating sighting device that applies to a shoulder-fired firearm where the firing mechanism and the sighting device are elevated above the stock butt when in a horizontal shooting position. This system comprises a cooperation between the rotating stock butt and the rotating sighting device that allows the firing mechanism and the barrel to be offset to either the right or to the left of the stock butt while the rotating sighting device and sight bead remains on the top center of the firearm. This allows the shooter to mount the gun with very little head movement.

摘要： The device (8) allows the release of a detachable magazine from the left and right side of the trigger housing of a firearm, and includes a left lever arm (6) pivotable about a left pivot pin (15) and a right lever arm (7) pivotable about a right pivot pin (14). The right lever arm includes a catch (9) to retain a magazine. The left lever arm (6) includes a left lever extension (12), and the right lever arm (7) includes a right lever extension (13), and these lever extensions are coupled together. When the right lever arm (7), together with its push-button (11), is pivoted to the right, the catch disengages and releases the magazine whilst the left lever arm (6) remains immobile. When the push-button (13) of the left lever arm (6) is pressed to the left, the left lever arm (6) and its left lever extension (12) pivot to the left causing said left lever extension (12) to push the right lever extension (13), and thus the right lever arm (7), to the right, which in turn causes the catch (9) to disengage and release the magazine.

摘要： An ambidextrous magazine catch for a firearm has a body movable on the frame of the firearm. A dog is rotatably mounted on the body. The dog has a jaw which is movable toward and away from the magazine well upon either motion of the body or rotation of the dog. The jaw engages a magazine in the magazine well. A plunger engaged with the body effects rotation of the dog through a cam surface on the plunger and a cam follower on the dog.
