## Abstract

In one aspect, a gun sight may include a main body and a light tube. In one embodiment, the main body may include an elongated light tunnel housing and a base, wherein the light tunnel housing is formed on top of the base, and a light tunnel is formed inside the light tunnel housing. The light tunnel has a front end and a rear end, and the light tube is disposed at the rear end. In one embodiment, the light tube can be a fluorescent optical fiber that can be used as a light source for the shooter's eye even when the environment is relatively dark. In other embodiments, the light tube can be an integration of optical fiber and tritium. The light tunnel is tapered from the front end to the rear end to enhances the effect of light concentration in the light tunnel.

## Claims

### Claim 1

A gun sight comprising:
a light tube; and
a main body including an elongated tapered light tunnel housing and a base; said light tunnel housing formed on top of the base, and a light tunnel formed inside the light tunnel housing; said light tunnel having a front end and a rear end;
wherein the light tunnel is tapered from the front end to the rear end to enhance light concentration in the light tunnel so the size of the light tunnel can be shortened and the size of the gun sight can be further minimized,
wherein the shape of the light tunnel is selected from a group consisting of triangle, circle or other polygons.

### Claim 2 (depends on 1)

The gun sight of claim 1, wherein the light tube is a fluorescent optical fiber that can be used as a light source for the shooter's eye even when the environment is relatively dark.

### Claim 3 (depends on 1)

The gun sight of claim 1, wherein the light tube is an integration of optical fiber and tritium.

### Claim 4

A method for aiming a target with a firearm comprising steps of:
providing a gun sight attached to a firearm; said gun sight having:
a main body; and
a light tube,
wherein main body includes an elongated tapered light tunnel housing and a base; the light tunnel housing is formed on top of the base, and a light tunnel is formed inside the light tunnel housing;
aiming the firearm at a selected target by slightly lifting up the firearm;
placing the target at a tip portion of the gun sight; and
adjusting a light spot at a rear end of the light tunnel to a center position inside the light tunnel.

### Claim 5 (depends on 4)

The method for aiming a target with a firearm of claim 4, wherein the shape of the light tunnel is, but not limited to triangle, circle or other polygons.

### Claim 6 (depends on 4)

The method for aiming a target with a firearm of claim 4, wherein the light tube is a fluorescent optical fiber that can be used as a light source for the shooter's eye even when the environment is relatively dark.

### Claim 7 (depends on 4)

The method for aiming a target with a firearm of claim 4, wherein the light tube is an integration of optical fiber and tritium.
