Abstract

A bedding block for mounting a barreled action for a rifle to a stock can include an elongated body configured to receive the barreled action for the rifle in a semicircular channel defined in top surface of the elongated body. The semicircular channel can have a first radius, the barreled action can have a second radius, and the first radius can be less than the second radius.

Claims

1. A bedding block for mounting a barreled action for a rifle to a stock, comprising:

an elongated body configured to receive the barreled action for the rifle in a channel of the elongated body, wherein;

the channel extends along a length of the elongated body,

the channel has a generally semicircular cross section,

the semicircular cross section has a radius and a center of curvature,

a portion of the barreled action configured to interface with the elongated body defines another radius, and

the radius of the semicircular cross section is less than the radius of the barreled action.

2. The bedding block of claim 1, wherein the channel is defined in an upper surface of the elongated body.

3. The bedding block of claim 1, wherein the channel includes opposing left and right sidewalls, a portion of each of which extends upwardly above the center of curvature.

4. The bedding block of claim 3, wherein a portion of each of the left and right sidewalls extends above the center of curvature from about 0.005 to about 0.030 inches.

5. The bedding block of claim 3, wherein the left and right sidewalls of the channel flex around the barreled action during introduction of the barreled action into the channel and grip the barreled action in an interference fit when the barreled action is seated in the channel.

6. The bedding block of claim 5, wherein the left and right sidewalls of the channel return to an original rest position when the barreled action is removed from the channel.

7. The bedding block of claim 2, wherein the center of curvature is below a horizontal plane containing the upper surface of the elongated body.

8. The bedding block of claim 1, wherein the radius of the semicircular cross section of the channel is from about 0.25% to about 10% less than the radius of the barreled action.

9. The bedding block of claim 1, wherein the radius of the semicircular cross section of the channel is about 0.25 to about 1.50 inches.

10. The bedding block of claim 1, wherein a bottom surface of the channel includes textural features configured to interface with the portion of the barreled action defining the radius of the barreled action.

11. The bedding block of claim 1, further comprising a clamp assembly configured to selectively apply a compressive retaining force to a recoil lug of the barreled action when the barreled action is received in the channel of the elongated body.

12. The bedding block of claim 11, wherein:

the clamp assembly comprises;

a threaded fastener having a head portion and an elongated portion,

a wedge member having top surface, a bottom surface, a generally vertical rear surface, a forward surface spaced from the rear surface, the forward surface having an upward slope, and a threaded aperture in which the elongated portion of the threaded fastener is matingly receivable extending parallel to the slope of the forward surface upward from the bottom surface to the top surface,

a slot in which the recoil lug of the barreled action is receivable defined in a forward portion of the elongated body,

a recess in which the wedge member is receivable defined in the forward portion of the elongated body forward of and adjacent to the slot, the recess having an upwardly sloped forward wall, and

a through hole extending from a bottom surface of the elongated body to a floor of the recess, the through hole sharing an axis with the threaded aperture when the wedge member is received in the recess; and

selectively tightening the threaded fastener when the recoil lug is received in the slot and the threaded fastener extends through the through hole and into the threaded aperture of the wedge member translates the wedge member down the sloped forward wall of the recess to apply a compressive retaining force to the recoil lug.

13. The bedding block of claim 12, wherein the wedge member has a cross section generally forming a right trapezoid.

14. The bedding block of claim 12, wherein the clamp assembly further includes an adaptor plate and at least one fastener for fastening the adaptor plate to the vertical rear surface of the wedge member.

15. A stock assembly configured to mount a barreled action for a rifle, the stock assembly comprising:

a stock having an elongated recess defined in an upper surface thereof; and

a bedding block rigidly secured in the elongated recess of the stock, the bedding block including an elongated body configured to receive the barreled action for the rifle in a channel defined in the elongated body, wherein the channel has a first radius, the barreled action has a second radius, and the first radius is less than the second radius.

16. The stock assembly of claim 15, wherein:

the channel extends along a length of the elongated body,

the channel has a semicircular cross section,

the semicircular cross section of the channel defines the first radius,

the second radius is defined by a portion of the barreled action that interfaces with the channel.

17. The stock assembly of claim 15, wherein:

the semicircular cross section of the channel has a center of curvature, and

the channel includes opposing left and right sidewalls that extend upwardly above the center of curvature.

18. The stock assembly of claim 15, further comprising:

a clamp assembly configured to selectively apply a compressive retaining force to a recoil lug of the barreled action when the barreled action is received in the channel of the elongated body, wherein the clamp assembly includes;

a threaded fastener having a head portion and an elongated portion,

a wedge member having top surface, a bottom surface, a generally vertical rear surface, a forward surface spaced from the rear surface, the forward surface having an upward slope, and a threaded aperture in which the elongated portion of the threaded fastener is matingly receivable extending parallel to the slope of the forward surface upward from the bottom surface to the top surface,

a slot in which the recoil lug of the barreled action is receivable defined in a forward portion of the elongated body,

a recess in which the wedge member is receivable defined in the forward portion of the elongated body forward of and adjacent to the slot, the recess having an upwardly sloped forward wall, and

a through hole extending from a bottom surface of the elongated body to a floor of the recess, the through hole sharing an axis with the threaded aperture when the wedge member is received in the recess;

wherein selectively tightening the threaded fastener when the recoil lug is received in the slot and the threaded fastener extends through the through hole and into the threaded aperture of the wedge member translates the wedge member down the sloped forward wall of the recess to apply a compressive retaining force to the recoil lug.

19. A method of mounting a barreled action for a rifle to a stock, comprising:

providing a bedding block including an elongated body configured to receive the action for the rifle in a semicircular channel defined in the elongated body, wherein the channel has a first radius, the barreled action has a second radius, and the first radius is less than the second radius;

providing a stock having a recess in which the bedding block is receivable;

securing the bedding block in the recess of the stock; and

fastening the barreled action for the rifle in the channel of the bedding block.

20. The method of claim 19, wherein:

the channel of the bedding block extends along a length of the elongated body,

the channel has a semicircular cross section,

the semicircular cross section of the channel defines the first radius,

a portion of the barreled action interfaces with three different portions of a bottom surface of the channel, and

the second radius is defined by the portion of the barreled action which interfaces with the bottom surface of the channel.
