ADJUSTABLE STOCK FOR FIREARM
First Claim
1. An adjustable stock assembly for a firearm, the stock comprising:
- a longitudinal axis;
a chassis comprising a main body configured for mounting a receiver and an axially elongated rear mounting extension extending rearwardly from the main body;
a butt pad assembly slideably coupled to the rear mounting extension, the butt pad assembly slideable between a plurality of axial positions on the rear mounting extension for adjusting a length of pull of the firearm;
a cheek rest slideably coupled to the rear mounting extension, the cheek rest slideable between a plurality of vertical positions on the rear extension; and
a locking mechanism coupled to the rear mounting extension and changeable between a locked and unlocked position, the locking mechanism configured to simultaneously lock both the butt pad assembly in one of the axial positions and the cheek rest in one of the vertical positions respectively.

Abstract
An adjustable stock for a firearm includes a longitudinally-extending chassis supporting a receiver, a butt pad assembly adjustable in longitudinal position for varying the length of pull, and a cheek rest. The cheek rest is adjustable in longitudinal and vertical positions. A triple-acting locking mechanism having locked and unlocked positions is operable to simultaneously lock the butt pad assembly in longitudinal position and the cheek rest in both longitudinal and vertical positions. The locking mechanism may be a cam lever assembly in non-limiting examples having a pivotable cam lever operable to simultaneously unlock or lock the butt pad assembly and cheek rest, thereby providing a single point of operation for making all the foregoing stock adjustments.

16. An adjustable stock assembly for a firearm, the stock comprising:
-
a longitudinal axis; a chassis comprising a main body configured for mounting a receiver and an axially elongated rear mounting extension extending rearwardly from the main body; a cam lever assembly mechanically coupled to the rear mounting extension, the cam lever assembly comprising a cam lever pivotably movable between a locking position and a release position; the cam lever assembly further comprising a pair of spring-biased clamping blocks coupled to the rear mounting extension, the clamping blocks laterally movable together and apart via operation of the cam lever between a closed position and an open position; a butt pad assembly comprising an elongated butt pad and an adjustment rail protruding axially forward from the butt pad into a longitudinal cavity of the rear mounting extension of the chassis, the adjustment rail received between the clamping blocks and slideable between a plurality of axial positions for adjusting a length of the butt pad; the clamping blocks when in the closed position lockingly engaging the adjustment rail in one of the axial positions, and when in the open position allowing the adjustment rail to slide axially relative to the rear mounting extend between the axial positions; and a cheek rest slideably mounted to the rear mounting extension, the cheek rest slideable between a plurality of vertical positions on the rear extension; the cam lever assembly operable to simultaneously lock both the butt pad assembly and cheek rest in one of the axial positions and vertical positions respectively. - View Dependent Claims (17, 18, 19, 20, 21)
