A rest for a pistol having a takedown passage and defining a major side plane. The rest comprises a post configured to be closely received by the passage; a planar rest element pivotally connected to the post and movable between an active position perpendicular to the side plane and a retracted position parallel to the side plane; and the rest element being biased to the active position.

A rifle stock is configured to receive a barreled action having an attached barrel and a lower surface which also has a downward protrusion. A shell having an exterior surface defines an exterior and an interior of the stock. The shell has opposed sidewalls extending from a bottom portion and an intermediate portion. A span element which is preferably a planar element and at least in part encompassed by fill material spans between the opposed sidewalls. The span includes a structural element that connects to the shell, a transverse intermediate portion, vertical end portions, and a forward edge for a protrusion receptacle which is defined in part by fill material in the stock and in part by the span element. The protrusion receptacle receives a downward extending protrusion of the rifle action. The fill may comprise rigid foam, composite materials, carbon fiber, or combinations of these materials.

A buffer tube for a firearm can include a body defining an interior cavity for receiving a buffer spring and a rail disposed on and/or formed from the outer surface of the body. The rail can include one or more pin holes configured to receive a pin of a stock to lock the stock in a position. The buffer tube can also include a slide bar channel defined through at least a portion of the rail and configured to allow a slide bar to slide therein relative to the one or more pin holes to urge a pin out of a respective pin hole and/or to block a pin from being received by the pin holes.

A firearm recoil system is disclosed. The firearm recoil system may include first and second guide rods attached to a bolt carrier group. The first and second guide rods may extend forward through an upper receiver. The firearm recoil system also may include first and second recoil springs. The first recoil spring may be disposed around the first guide rod, and second recoil spring may be disposed around the second guide rod.

The present invention relates to an active system configured to apply an active force to a portion of a firearm designed to contact a body of the firearm's operator, to reduce the perceived recoil of the firearm. The active system includes an actuation element capable of generating an active force, and systems for powering and selectively operating the actuation element.

A chassis locking system includes a bolt having a cross pin and a chassis. The chassis includes a helically inclined surface that contacts the cross pin of the bolt as the bolt is turned, tightening the chassis to a rifle stock.

A thumb rest mechanism for a firearm having a frame, providing a thumb rest mount secured to the frame and having a mount member defining a mount surface. A thumb rest being releasably secured to the mount member in engagement with the mount surface and having a thumb engaging surface oriented at a suitable angle for recoil resisting engagement by the thumb of a firearm user and being of roughened character for non-slip engagement by the thumb of the firearm user. A protective plate extending from the thumb rest a protecting the users thumb from contact and potential damage by a moveable firearm component.
