US12607431 - Structures for firearms

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.

firearmbuffer tubestock system

The patent describes a buffer tube for firearms that features an interior cavity for a buffer spring and an outer rail with pin holes for locking a stock in position. Additionally, it includes an actuator system allowing a user to adjust the stock’s position using a single hand, facilitating seamless operation without compromising grip or trigger access.

Claim 1

1 . An actuator for a stock system for a firearm, comprising: an actuator body including one or more actuator arms configured to connect to a sliding stock of a stock system for a firearm; and one or more actuator lands extending from a distal end of a respective actuator arm, the one or more actuator lands comprising: a first side having a first shape; and a second side having a second shape different than the first shape, the second side having a flat and/or planar shape defined in a plane orthogonal to a direction of actuation of the actuator body, wherein the one or more actuator lands are actuatable by a first digit of a user’s gripping hand to actuate the stock system to cause the sliding stock to move between a collapsed position and an extended position without the user having to remove the same hand from a grip of the firearm and/or without removing another digit of the same hand from a trigger of the firearm. wherein the one or more actuator lands are actuatable by a first digit of a user’s gripping hand to actuate the stock system to cause the sliding stock to move between a collapsed position and an extended position without the user having to remove the same hand from a grip of the firearm and/or without removing another digit of the same hand from a trigger of the firearm.
