Abstract

An adjustable stock and cheek rest assembly for a firearm includes a buffer tube extending rearwardly from the firearm at an angle relative to the firearm receiver. A stock is slidably mounted on the buffer tube, and a cheek rest is disposed in overlying relationship to the stock. A cheek rest adjustment arrangement is connected between the stock and the cheek rest, and is provided with a movable linkage for enabling vertical movement of the cheek rest relative to the stock as the stock moves along the angled buffer tube. A movable member provided with locking structure is mounted on the stock for selective engagement with lock receiving structure on the buffer tube for locking the stock in various axial adjustment positions along the buffer tube.

Claims

1. An adjustable stock and cheek rest assembly for a firearm comprising:

a support member connected to the firearm and provided with lock receiving structure thereon;

a stock slidably mounted on the support member;

a cheek rest disposed in overlying relationship to the stock;

a cheek rest adjustment arrangement connected between the stock and the cheek rest, and provided with a movable linkage for enabling vertical adjustment of the cheek rest relative to the stock; and

a movable member provided with locking structure and mounted on the stock for selective engagement with the lock receiving structure for locking the stock and the cheek rest in various axial adjustment positions along the support member.

2. The adjustable stock and cheek rest assembly of claim 1, wherein the movable linkage is an expandable and collapsible scissors linkage.

3. The adjustable stock and cheek rest assembly of claim 1, wherein the cheek rest adjustment arrangement includes an adjustment device, and the linkage is movable in response to actuation of the adjustment device.

4. The adjustable stock and cheek rest assembly of claim 3, wherein the adjustment device enables incremental adjustment and locking of the cheek rest relative to the stock.

5. The adjustable stock and cheek rest assembly of claim 3, wherein the adjustment device is rotatable and includes a cheek wheel coupled to a lift pin operably connected to the linkage.

6. The adjustable stock and cheek rest assembly of claim 5, wherein the cheek rest adjustment arrangement includes a lift rod located between the cheek wheel and the lift pin.

7. The adjustable stock and cheek rest assembly of claim 1, wherein the support member is a buffer tube extending rearwardly from the firearm.

8. The adjustable stock and cheek rest assembly of claim 7, wherein the lock receiving structure is a series of spaced apart cylindrical recesses formed in a bottom surface of the buffer tube.

9. The adjustable stock and cheek rest assembly of claim 1, wherein the stock is provided with a butt pad assembly at a rearward end thereof.

10. The adjustable stock and cheek rest assembly of claim 8, wherein the movable member includes a lever connected to a spring biased latch pin with a cylindrical portion that is engageable and disengageable with the cylindrical recesses on the buffer tube.

11. An adjustable stock for a firearm having a receiver and a gas tube extending downwardly at an angle relative to the receiver comprising:

a buffer tube extending rearwardly from the receiver and surrounding the gas tube and including a series of recesses formed in a bottom surface thereof;

a stock having one end slidably mounted for axial movement on the buffer tube, and an opposite end provided with a butt pad assembly; and

a lever arrangement movably mounted on the stock and provided with a spring biased latch pin which is selectively engageable and disengageable with any one of the recesses on the buffer tube for locking the stock in various axial adjustment positions along the buffer tube.

12. The adjustable stock of claim 11 wherein the buffer tube is secured to the firearm and the stock is movable along the buffer tube such that the stock moves along the angled gas tube.

13. The adjustable stock of claim 12 further comprising a cheek rest adjustment arrangement connected between the stock and a check rest to independently adjust the cheek rest relative to the stock independent of the movement of the stock relative to the buffer tube.

14. The adjustable stock of claim 13, wherein rotation of the adjustment device results in incremental adjustment and locking of the cheek rest relative to the stock.

15. The adjustable stock assembly of claim 11, wherein the adjustment device is accessible for movement between a rearward end of the cheek rest and the butt pad assembly.

16. An adjustable stock for a firearm having a receiver comprising:

a buffer tube extending rearwardly from the receiver and including a series of recesses formed in a bottom surface thereof;

a stock having one end slidably mounted for axial movement along the buffer tube and an opposite end provided with a butt pad assembly;

a tension device positioned between the stock and the buffer tube to selectively adjust the interference fit between the buffer tube and the stock; and

a lever arrangement movably mounted on the stock to selectively engage and disengage with any one of the recesses on the buffer tube for locking the stock in various axial adjustment positions along the buffer tube.

17. The adjustable stock of claim 16 wherein the tension device is mounted within the stock and frictionally engages the buffer tube.

18. The adjustable stock of claim 16 further comprising a cheek rest disposed in an overlying relationship to the stock.

19. The adjustable stock of claim 18 wherein the cheek rest is adjustable independent of the movement of the stock along the buffer tube.

20. The adjustable stock of claim 16 wherein the tension device is adjustable prior to mounting of the stock along the buffer tube.
