A firearm including a barrel bushing is disclosed. The barrel bushing provides for guidance of the slide without a need for forward rails. The barrel bushing is retained by a bushing stop that allows the slide to be removed while the recoil spring and bushing are retained on the barrel.

Embodiments of the disclosure relate to semi-automatic, automatic, and bolt-action firearms and components for such firearms.

A semiautomatic slide pin removal tool that includes a handle member, and a tube extending perpendicular to, and outwards from, the handle member and having a distal end including a variety of different pin receivers for pushing and removing slide stop lever pins of a slide assembly on semiautomatic pistols. The pin receivers effectively and efficiently engage and mate with heads of slide stop lever pins to prevent the distal end of the slide pin removal tool from slipping or sliding off the heads of the slide stop lever pins during use. In practice, users firmly grasp an automatic pistol in one hand while negotiating the slide pin removal tool with fingers to push and remove slide stop lever pins from semiautomatic pistols with ease while freeing use of the other hand.

An upper receiver assembly of a firearm is disclosed. The upper receiver assembly contains a barrel, an extension block removably coupled with the barrel, an upper receiver removably coupled with the extension block, a handguard mounting block removably coupled with the barrel, and a handguard removably coupled with the handguard mounting block.

Takedown pins for rifles have a pin movable in a direction along its length between an operating condition and a released condition. The pin has a first end portion that prevents relative movement of the upper receiver with respect to the lower receiver when the pin is in the operating condition. The first end portion has a lower end portion surface adapted to resist upward movement of the upper receiver's lug. The pin has an intermediate portion adjacent to the lower end portion surface defining a lower channel having a lower channel surface above the level of the lower end portion surface. When the pin is in the released condition, the lower channel is registered with the lug, and the lug is enabled to move upward with respect to the lower receiver by a limited distance to a disengaged position.

An improved pivot pin for a firearm may provide a head, shank, and/or openings. The improved pivot pin may also provide a modified central channel, an installation point, and/or installation channel to allow for tool-free or tool-less installation. Further, the improved pivot pin may provide a removal channel to allow the pivot pin to easily be removed from the lower receiver without tools. An improved takedown pin for a firearm may provide a head, shank, and/or openings. The improved takedown pin may also provide a modified center channel and/or removal channel as well. A removal tool to aid removal of a pivot pin or takedown pin from a firearm may be generally shaped to conform or fit within the channel of the pivot or takedown pin. The width and height of the removal tool may be slightly smaller than the width and height of the channel of the pivot pin or takedown pin. The distal end of the removal tool may taper from a top surface to the bottom surface to form a sharp point or tip. A shank of any conventional or aftermarket pivot pin, takedown pin, or reinstallation tool may be modified to provide a storage cavity sized to receive the removal tool.
