Abstract

A firearm attachable bullet trap for use on a gas operated firearm having a compensator attached to the barrel. The bullet trap captures bullets from live rounds and provides an visual and tactile indication of live rounds having been fired. The bullet trap is designed for the shooting of blank rounds, but is adapted to handle live rounds having a bullet in a semi-automatic or automatic firearm.

Claims (50)

1. A bullet trap for use on a gas operated firearm having a compensator attached to a barrel, the bullet trap comprising:

a body for engaging said compensator;

a spigot attached to said body, the spigot having a spigot bore extending from a rear end towards a front end;

a ballistic plate chamber proximate the front end of the spigot, distal said compensator, the ballistic plate chamber housing a ballistic plate;

a bullet trap chamber, and at least one bullet trap orifice extending between the ballistic plate chamber and the bullet chamber;

at least one gas track extending between the ballistic plate chamber and the atmosphere; and

an impact indicator operatively connected with the ballistic plate, the impact indicator provides visual and tactile indications of when the ballistic plate has received the impact of a bullet,

wherein the firearm attachable bullet trap operates as a blank firing attachment with blank rounds and as a bullet trap with ball rounds.

2. The bullet trap of claim 1 , wherein the spigot bore further comprising a solid end, distal said compensator.

3. The bullet trap of claim 1 , wherein the ballistic plate moves between a ready position and an impacted position when a bullet impacts upon the ballistic plate.

4. The bullet trap of claim 3 , wherein the ballistic plate substantially seals off the bullet trap orifice when in the ready position and substantially opens the bullet trap orifice when in the impacted position.

5. The bullet trap of claim 3 , wherein the ballistic plate substantially seals off the at least one gas track when in the ready position and substantially opens the at least one gas track when in the impacted position.

6. The bullet trap of claim 1 , wherein the spigot bore reduces in diameter through a plurality of steps.

7. The bullet trap of claim 6 , wherein said plurality of steps comprises three steps, whereby at least two steps have a diameter less than a diameter of the bullet.

8. The bullet trap of claim 1 , wherein said at least one gas track comprises two gas tracks.

9. The bullet trap of claim 1 , wherein the spigot is threadably movable relative to the body.

10. The bullet trap of claim 1 comprising a gas escape connected to said bullet trap chamber, said gas escape diffuses gas and particles away from the line of fire as well as reduces velocity.

11. The bullet trap of claim 10 wherein the gas escape is an S-shaped gas escape around the circumference of the bullet trap.

12. The bullet trap of claim 7 wherein the three steps comprise:

a first step designed to strip the bullet of a bullet jacket;

a second step designed to separate material from the bullet and compress steel penetrator; and

a third step designed to further reduce the diameter, mass and velocity of projectiles.

13. A bullet trap for use on a gas operated firearm having a compensator attached to a barrel, comprising:

a body for engaging said compensator;

a spigot attached to said body, the spigot having a spigot bore extending from a rear end towards a front end;

a ballistic plate chamber proximate the front end of the spigot, distal said compensator, the ballistic plate chamber housing a ballistic plate;

a bullet trap chamber, and at least one bullet trap orifice extending between the ballistic plate chamber and the bullet chamber;

at least one gas track extending between the ballistic plate chamber and the atmosphere; and

a gas escape connected to said bullet trap chamber, the gas escape diffuses gas and particles away from the line of fire as well as reduces velocity,

wherein the firearm attachable bullet trap operates as a blank firing attachment with blank rounds and as a bullet trap with ball rounds;

further comprising an impact indicator operatively connected with the ballistic plate, the impact indicator provides visual and tactile indications of when the ballistic plate has received the impact of a bullet.

14. The bullet trap of claim 13 wherein the spigot bore reduces in diameter through three steps, the three steps comprising:

a first step designed to strip the bullet of a bullet jacket;

a second step designed to separate material from the bullet and compress steel penetrator; and

a third step designed to further reduce the diameter, mass and velocity of projectiles.

15. The bullet trap of claim 13 wherein the gas escape is an S-shaped gas escape around the circumference of the bullet trap.

16. A method for trapping a bullet from a gas operated firearm having a compensator attached to a barrel, the method comprising:

receiving the bullet through a bore extending from a rear end towards a front end of a spigot of a bullet trap;

reducing the velocity and compressing particulates of the bullet through the bore;

creating impact with a ballistic plate housed within a ballistic plate chamber proximate to the front end of the spigot;

visually and tactily indicating the impact of the bullet when the bullet has been received by the ballistic plate;

venting through at least one bullet trap orifice to a bullet trap chamber, via a gas track extending between the ballistic plate and the atmosphere, gas and particulates created from the impact of the bullet against the ballistic plate;

storing some of the bullet material in the bullet trap chamber; and

diffusing remaining gas and particulates through a gas escape.

17. The method of claim 16 , wherein creating impact with the ballistic plate moves the plate from a ready position to an impacted position.

18. The method of claim 16 , wherein the bore for receiving the bullet reduces in diameter through three steps, the three steps comprising:

a first step designed to strip the bullet of a bullet jacket;

a second step designed to separate material from the bullet and compress steel penetrator; and

a third step designed to further reduce the diameter, mass and velocity of projectiles.

19. The method of claim 16 wherein diffusing remaining gases and particulates comprises forcing the gas and escaping particulates through an S-shaped gas escape around the circumference of the bullet trap.
