Abstract

A recoil dampening device for a gun sight includes a first rail member adapted to fixedly mount to a firearm, wherein the first rail member has an elongated body portion and a pair of mounting flanges extending outwardly from and longitudinally along the body portion, and a second rail member having an elongated downwardly opening channel that slidably receives the body portion and mounting flanges of the first rail member therein, wherein the second rail member is adapted to releasably support a gun sight thereon. The sight base also includes at least one deformable recoil absorbing member disposed between the first rail member and the second rail member, wherein the recoil absorbing member is adapted to reduce the recoil transferred from the firearm to the gun sight when the firearm is fired.

9. The sight base of claim 8, wherein the first recoil absorbing member and the second recoil absorbing member each include a coil spring.

10. A recoil dampening sight base, comprising:

a first rail member adapted to fixedly mount to a firearm, the first rail member having an elongated body portion and a pair of mounting flanges extending outwardly from and longitudinally along the body portion;

a second rail member having an elongated downwardly opening channel that slidably receives the body portion and mounting flanges of the first rail member therein, the second rail member adapted to releasably support a gun sight thereon; and

a first stop member attached to a first end of the second rail;

a second stop member attached to a second end of the second rail;

at least one elastically deformable recoil absorbing member disposed between the first rail member and the second rail member, wherein the at least one recoil absorbing member includes a first absorbing member and a second absorbing member, the first absorbing member is located between the first stop member and a first end of the first rail member, the second absorbing member is located between the second stop member and a second end of the first rail member, and wherein the recoil absorbing member is adapted to reduce the recoil transferred from the firearm to the gun sight when the firearm is fired.

11. The sight base of claim 10, wherein the first stop member and the second stop member are each received within the channel of the second rail member.

12. The sight base of claim 11, wherein the first and second stop members each include a body portion and a pair of mounting flanges extending outwardly from the body portion, and wherein the first and second stop members may be slidably received within the channel of the second rail member and then fixedly attached to the second rail member.

13. The sight base of claim 10, wherein the first end of the first rail member includes a longitudinally extending bore the receives at least a portion of the first recoil absorbing member therein, and wherein the second end of the first rail member includes a longitudinally extending bore that receives at least a portion of the second recoil absorbing member therein.

14. The sight base of claim 10, wherein the first recoil absorbing member and the second recoil absorbing member each include a coil spring.

15. A firearm for reducing the recoil as transferred to a gun sight mounted thereon, comprising:

body portion of a firearm having an upper surface;

a first rail member fixedly mounted to the upper surface of the firearm, the first rail member having an elongated body portion and a pair of mounting flanges extending outwardly from and longitudinally along the body portion;

second rail member having an elongated downwardly opening channel that slidably receives the body portion and mounting flanges of the first rail member therein, and at least one receiving rail adapted to slidably receive the gun sight thereon;

at least one elastically deformable recoil absorbing member disposed between the first rail member and the second rail member, wherein the recoil absorbing member is adapted to reduce the recoil transferred from the firearm to the gun sight when the firearm is fired; and

a gun sight releasably mounted with the second rail member.

16. The firearm of claim 15, wherein the receiving rail of the second rail member includes a body portion and a pair of mounting flanges extending outwardly from the body portion.
