Abstract

A expansion chamber assembly for a firearm is disclosed. The expansion chamber contains an outer tube containing a front end and a rear end, a front cap coupled with the outer tube at the front end, a rear cap coupled with the outer tube at the rear end, an inner tube retained within the outer tube by the front cap and the rear cap, wherein the inner cap contains one or more through apertures to allow expanding gasses to move from the inner tube into the outer tube, and one or more exit apertures to allow expensing gases to exit the expansion chamber assembly.

Claims (23)

1. A expansion chamber assembly for a firearm, the expansion chamber assembly comprising:

an outer tube comprising a front end and a rear end;

a front cap coupled with the outer tube at the front end;

a rear cap coupled with the outer tube at the rear end, wherein the rear cap comprises an inner thread configured to engage at least a portion of an outer thread on an exit end of a barrel; and

an inner tube removably retained within the outer tube by the front cap and the rear cap, wherein the inner tube comprises one or more through apertures to allow a portion of expanding gasses to move from the inner tube into the outer tube;

wherein the portion of expanding gases move from the inner tube into the outer tube through one or more through apertures;

wherein the portion of expanding gasses move from the outer tube to outside the expansion chamber assembly directly through one or more exit apertures located in the rear cap.

2. The expansion chamber assembly of claim 1 further comprising a sound absorbing materials positioned between the inner tube and the outer tube.

3. The expansion chamber assembly of claim 1 , wherein the one or more through apertures allow expanding gasses to move from the inner tube directly into the outer tube.

4. A expansion chamber assembly for a firearm, the expansion chamber assembly comprising:

an outer tube comprising a front end and a rear end;

a front cap coupled with the outer tube at the front end;

a rear cap coupled with the outer tube at the rear end; and

an inner tube removably retained within the outer tube by the front cap and the rear cap, wherein the inner tube is positioned between the front cap and the rear cap;

wherein the rear cap comprises a first through aperture to allow expanding gasses to move from a barrel into the inner tube;

wherein the inner tube comprises one or more through apertures to allow a portion of the expanding gasses to move from the inner tube into the outer tube; and

wherein the rear cap comprises one or more exit apertures to allow the portion of the expanding gases to exit the expansion chamber assembly.

5. The expansion chamber assembly of claim 4 , wherein expanding gasses moving from the barrel into the inner tube travel in a direction that is opposite to the portion of the expanding gases that exit the expansion chamber assembly through the one or more exit apertures.

6. The expansion chamber assembly of claim 4 , wherein the portion of the expanding gases exit the expansion chamber assembly adjacent to where the expanding gasses move from the barrel into the inner tube.

7. The expansion chamber assembly of claim 1 , wherein the rear cap comprises an outer thread for removably coupling with an inner thread of the outer tube.

8. The expansion chamber assembly of claim 4 , wherein the rear cap comprises an outer thread for removably coupling with an inner thread of the outer tube.

9. The expansion chamber assembly of claim 1 , wherein the front cap comprises an outer thread for removably coupling with an inner thread of the outer tube.

10. The expansion chamber assembly of claim 4 , wherein the front cap comprises an outer thread for removably coupling with an inner thread of the outer tube.
