Abstract
A firearm stock includes a stock body slidably mounted on a beam. A lever attached to the stock body can be moved between a locked position and at least one unlocked position, where operating the lever moves a locking mechanism between locked and unlocked positions. For example, when the lever is in a first unlocked position, the locking mechanism permits longitudinal adjustment of the stock body along the beam. When the lever is in a second unlocked position the locking mechanism permits the stock body to be slidably removed from the beam. In one example, the lower portion of the stock body defines a plurality of cam pathways for pins that secure the lever to the stock body. Forward cam pathways permit either a pivoting movement about the rear pin or a downward and forward shifting movement.
