Abstract

A switch barrel recoil lug for clamping together a rifle action and a rifle barrel having a body with a barrel shank bore hole and a split section allowing expansion and contraction of the barrel shank bore hole, an index pin hole or threaded holes for aligning and connecting the body to the rifle action and a stock flange for engaging a rifle stock wherein the barrel shank bore hole has a tapered surface matching a tapered surface on a barrel shank of the rifle barrel.

Claims

1. A switch barrel recoil lug for clamping together a rifle action and a rifle barrel comprising:

a body having a barrel shank bore hole and at least one split section allowing expansion and contraction of the barrel shank bore hole;

means for aligning and connecting the body to the rifle action; and

a stock flange for engaging a rifle stock,

wherein the barrel shank bore hole has a tapered surface matching a mating tapered surface on a barrel shank of the rifle barrel.

2. The recoil lug of claim 1 wherein the means for aligning and connecting the body to the rifle action include an index pin hole for receipt of an index pin on the rifle action.

3. The recoil lug of claim of claim 1 wherein the means for aligning and connecting the body to the rifle action include at least one threaded hole through the body and the rifle action for receipt of a threaded screw.

4. The recoil lug of claim 1 wherein the split section of the body includes a top flange having a threaded bore and a clamping bolt positioned in the threaded bore.

5. The recoil lug of claim 1 wherein the split section of the body includes a top portion and a separate bottom portion spaced from the top portion, each having aligned threaded bores on either side of the barrel shank bore hole for receipt of a clamping bolt.

6. A switch barrel recoil lug for clamping together a rifle action and a rifle barrel comprising:

a body portion having a barrel shank bore hole extending therethrough;

a top flange portion extending above the body portion having a split section extending into the barrel shank bore hole, the top flange portion having a threaded bore extending therethrough and a threaded bolt positioned in the threaded bore to expand and contract a diameter of the barrel shank bore hole;

means for aligning and connecting the body portion to the rifle action; and

a stock flange portion extending below the body portion for engaging a rifle stock.

7. The recoil lug of claim 6 wherein the means for aligning and connecting the body portion to the rifle action includes an index pin hole for receipt of an index pin on the rifle action.

8. The recoil lug of claim 6 wherein the means for aligning and connecting the body portion to the rifle action includes at least one threaded hole extending through the body portion and the rifle action for receipt of a threaded screw.

9. The recoil lug of claim 6 wherein the barrel shank bore hole has a tapered surface for engaging a mating tapered surface on a barrel shank of the rifle barrel.

10. A switch barrel recoil lug for clamping together a rifle action and a rifle barrel comprising:

a top body portion;

a separate body portion spaced from the top body portion;

the top body portion and the bottom body portion forming a barrel shank bore hole for receipt of a barrel shank of the rifle barrel;

the top body portion and the bottom body portion having an aligned threaded hole on either side of the barrel shank bore hole for receipt of a clamping screw;

means for aligning and connecting the bottom body portion to the rifle action; and

a stock flange portion extending below the bottom body portion for engaging a rifle stock.

11. The recoil lug of claim 10 wherein the means for aligning and connecting the bottom body portion to the rifle action includes an index pin hole for receipt of an index pin on the rifle action.

12. The recoil lug of claim 10 wherein the means for aligning and connecting the bottom body portion to the rifle action include at least one threaded hole extending through the bottom body portion for receipt of a threaded screw.

13. The recoil lug of claim 10 wherein the barrel shank bore hole has a tapered surface for engaging a mating tapered surface on the barrel shank.
