An adjustable stock for a firearm includes a fixed body attachable to the firearm and a moveable body slideably connected to the fixed body. The moveable body defines a butt of the stock. A hole may be defined in one of the fixed body and the moveable body that has a first side opening and a second side opening disposed opposite the first side opening. A position selector is disposed in the hole and includes a first selector body and a second selector body. The first selector body includes a body portion shaped as a button having an engagement surface and a protrusion extending away from the body portion. The second selector body includes a body portion shaped as a button having an engagement surface and a protrusion extending away from the body portion. A biasing device is disposed between the first and second selector bodies to bias the first and second selector bodies apart and so that the engagement surface of the first selector body extends from the first side opening and the engagement surface of the second selector body extends from the second side opening. Further, a plurality of locating slots is defined in the other of the fixed body and the moveable body. At least one of the protrusions of the first and second selector bodies engage one of the plurality of locating slots to selectively fix the relative position of the moveable body to the fixed body.
An adjustable stock for a firearm having a first side, a second side, and a bottom side. The stock includes a fixed body attachable to the firearm and a moveable body slideably connected to the fixed body. The second body includes a butt of the stock. A position selector is disposed to selectively fix the relative position of the moveable body to the fixed body. The position selector is disposed on one of a first side and a bottom side. A position retention device provides a second point of selective fixation between the fixed body and the moveable body. The position retention device is disposed on one of a first side and a bottom side.
A stock for a firearm includes an attachment member shaped to attach the stock to a firearm, a stock member pivotally attached to the attachment member so that the stock member is pivotable between an aligned position and a folded position, and a stock body.

An improved firearm having a barrel coupled to an upper receiver where the receiver includes a passageway extending generally parallel to the longitudinal axis, and a guidance feature extending along the passageway generally parallel to the longitudinal axis. The firearm also includes a lower receiver coupled to the upper receiver and a recoil spring assembly comprising a mating attachment structure and a disassembly button disposed on a lateral side of the upper receiver. The mating attachment structure is attached to an attachment structure of the lower receiver to attach the lower receiver to the upper receiver. Actuation of the disassembly button detaches the mating attachment structure from the attachment structure to detach the lower receiver from the upper receiver.
A multi-caliber ambidextrously controlled firearm that includes an adjustable ejection system to facilitate the ejection of spent cartridge casings from a firearm. The adjustable ejection system includes an ejection port defined by an aperture in the firearm and a deflector. The deflector is attached to the firearm to adjust the size of the ejection port and may be attached at one of at least two attachment positions of the firearm. The adjustable ejector system includes an ejector selectively attached to the firearm at one of at least two ejector attachment positions. The improved firearm also includes an ambidextrous magazine catch system for selectively retaining a magazine within a firearm. The magazine catch system includes a first button opposite a second button such that either button may be actuated by a user to release the magazine retained with the firearm.
A firearm including a barrel having a chamber and an integrally formed upper receiver having a passageway, an accessory rail extending the complete length of the upper receiver, and a guidance feature extending along the passageway. The firearm also includes an operating rod having an anti-bounce mechanism, a bolt that is rotated counter-clockwise to lock against the chamber, a bolt carrier having a safety extension disposed below the bolt that prevents a hammer from striking a firing pin until the bolt is locked against the chamber, a lower receiver, a recoil spring assembly, and a fire control group. The bolt includes a polymer spring that biases a sliding extractor against the base of a cartridge. The sliding extractor is disposed at an angle ranging from thirty degrees to fifteen degrees on the bolt face to provide a low ejection angle from the firearm.
