The adjustable cheek riser comprises a comb extension member configured to move between at least an expanded configuration and a retracted configuration. The adjustable cheek riser comprises at least one living hinge positioned on the comb extension member and at least one locking element, the at least one locking element being configured to switch between a locked and an unlocked position upon activation of the living hinge.

Claims

1. An adjustable cheek riser for a firearm comprising:

a comb extension member configured to move between at least an expanded configuration and a retracted configuration;

at least one living hinge positioned on the comb extension member; and

at least one pin, the at least one pin being configured to switch between a locked and an unlocked position upon activation of the living hinge.

2. The adjustable cheek riser of claim 1, wherein the at least one pin passes through a hole or slot on a surface in a lower portion of the comb extension member.

3. The adjustable cheek riser of claim 2, wherein the at least one pin is further configured to move into a pin recess for locking the position of the comb extension member.

4. The adjustable cheek riser of claim 3, wherein the at least one pin is further configured to slide along a pin track during switching between the expanded configuration and the retracted configuration.

5. The adjustable cheek riser of claim 4, wherein the comb extension member is configured to stop on at least one intermediate position between the expanded configuration and the retracted configuration.

6. The adjustable cheek riser of claim 1, wherein the at least one pin is a spring-loaded pin.

7. The adjustable cheek riser of claim 1, wherein the at least one living hinge is positioned on at least one side of the comb extension member.

8. The adjustable cheek riser of claim 7, wherein activation of the at least one living hinge is configured to release a locking mechanism and slide a tab along a groove.

9. The adjustable cheek riser of claim 8, wherein the tab and the groove are positioned at an angle of about 45 degrees with respect to the axis of firing.

10. The adjustable cheek riser of claim 1, wherein the comb extension member is positioned on a base.

11. The adjustable cheek riser of claim 10, wherein the base is positioned on a carrier.

12. The adjustable cheek riser of claim 11, wherein the base is secured on the carrier using a snap fit connection.

13. The adjustable cheek riser of claim 11, wherein the carrier is positioned at a rear end of a firearm.

15. The adjustable cheek riser of claim 14, wherein a tapered contour and a hole at a forward end of the extension mate the extension of the carrier to the rear end of the firearm.

16. The adjustable stock of claim 6, wherein the at least one pin is biased toward a locked position.

17. An adjustable cheek riser for a firearm comprising:

a comb extension member configured to move between at least an expanded configuration and a retracted configuration;

at least one button positioned on the comb extension member; and

at least one pin, the at least one pin being configured to switch between a locked and an unlocked position upon activation of the button.

18. A method for adjusting a cheek riser of a firearm, the method comprising:

pressing on a grip portion of at least one living hinge;

shifting a locking mechanism from a locked position to an unlocked position; and

moving the cheek riser to a desired height.

19. The method for adjusting a cheek riser of a firearm of claim 18, further comprising releasing the grip portion of the at least one living hinge.
