The U-shaped portion is biased against the lower portion, such that the walls of the U-shaped upper portion press against the lower portion, thereby locking the upper portion in position. A first release and a second release are depressed to release the bias and enable the upper portion to be raised and lowered relative to the lower portion. Interlocking mechanisms located on the upper and lower portions facilitate locking of the cheek rest in a position determined by the user. ## Claims ### Claim 1 An adjustable cheek rest for a firearm, the cheek rest comprising: a lower portion attached to or integral to the stock of a firearm, the lower portion defining a slot passing there through and having an outer surface; a resilient upper portion separable from the lower portion, the upper portion having a cross-sectional U shape including an open end and a curved end, the U-shaped upper portion having two sides each defining an aperture there through, the resilient upper portion exhibiting a preferred shape wherein an interior dimension between the two sides is less than a corresponding exterior dimension of the lower portion; and a compressible release mechanism configured to pass through the slot and the two apertures, wherein the release mechanism in an extended position allows the upper portion to grip the lower portion and when in a compressed position outwardly deforms the open end of the upper portion to release the grip and allow the upper portion to slide in relation to the lower portion. ### Claim 2 (depends on 1) The cheek rest of claim 1 wherein the compressible release attaches the upper portion to the lower portion. ### Claim 3 (depends on 1) The cheek rest of claim 1 comprising an adjustable void between the upper portion and the lower portion. ### Claim 4 (depends on 1) The cheek rest of claim 1 wherein the upper portion includes protrusions or depressions on an inner surface that interact with complementary protrusions or depressions on the outer surface of the lower portion. ### Claim 5 (depends on 1) The cheek rest of claim 1 wherein the cheek rest exhibits a range of vertical adjustment approximately equal to a length of the slot minus a diameter of the release. ### Claim 6 (depends on 1) The cheek rest of claim 1 wherein the release mechanism comprises a first release and a second release, the first release including a first knob and the second release including a second knob, the first knob extending outside of the aperture of one side and the second knob extending outside the aperture of the second side. ### Claim 7 (depends on 6) The cheek rest of claim 6 wherein the first release and the second release are slidable in relation to each other and are biased outwardly. ### Claim 8 (depends on 7) The cheek rest of claim 7 wherein the outwardly biased force is provided by the sides of the upper portion. ### Claim 9 (depends on 6) The cheek rest of claim 6 wherein the upper portion of the cheek rest is removed by disconnecting the first release from the second release. ### Claim 10 (depends on 4) The cheek rest of claim 4 wherein the protrusions comprise a series of ridges. ### Claim 11 (depends on 1) The cheek rest of claim 1 wherein the upper portion is comprised of a hypoallergenic polymer having adequate rigidity to avoid collapse when supporting a user's cheek in a firing position. ### Claim 12 (depends on 1) The cheek rest of claim 1 wherein the lower portion is integral to the stock. ### Claim 13 (depends on 1) The cheek rest of claim 1 wherein the apertures are located on a lower half of the upper portion and the user's cheek does not contact the release mechanism when the firearm is supported against the user's cheek in a firing position. ### Claim 14 (depends on 1) The cheek rest of claim 1 wherein the lower portion includes guides designed to complement one or more guides on the inner surface of the upper portion such that the interaction there between limits movement of the upper portion to a substantially vertical direction. ### Claim 15 (depends on 1) The cheek rest of claim 1 wherein the upper portion includes a spring clip to bias the upper portion in the preferred shape. ### Claim 16 (depends on 1) The cheek rest of claim 1 wherein the upper portion consists essentially of a homogeneous polymeric material. ### Claim 17 A method of adjusting a cheek rest for a firearm, the method comprising: pinching together two knobs positioned on opposing ends of a release mechanism; forcing the sides of a resilient cheek rest outwardly from a stock of the firearm; sliding the resilient cheek rest vertically from a first vertical position while pinching the knobs of the release mechanism; and releasing the knobs of the release mechanism to secure the resilient cheek rest in a second vertical position. ### Claim 18 (depends on 17) The method of claim 17 further comprising: separating a first knob from a second knob to remove the release mechanism from the stock; and removing the resilient cheek rest from the firearm. ### Claim 19 (depends on 17) The method of claim 17 wherein the two knobs are pinched together using a single hand. ### Claim 20 (depends on 17) The method of claim 17 wherein the method is performed using a single hand.
