Firearm suppressor and method of operation
A suppressor assembly for use with a firearm is disclosed herein. The suppressor having: a baffle; a rear seal plate; a housing; and a front end cap, wherein the housing, the rear seal plate and the front end cap define an expansion chamber for receipt of expansion gases received from the baffle.
1. A suppressor assembly for use with a firearm, comprising:
a baffle having a concentric bore extending therethrough from a threaded opening and a series of annular passageways extending from the concentric bore to a tapered exterior surface of the baffle, the series of annular passageways being axially inclined rearward with respect to a rearward end of the baffle;
a rear seal plate;
a housing; and
a front end cap, wherein the housing, the rear seal plate and the front end cap define an expansion chamber for receipt of expansion gases received from the baffle.
2. The suppressor assembly as in claim 1 , wherein the baffle is a monolithic structure and has a cone shape that increases in diameter as the baffle extends forwardly towards, the front end cap.
3. The suppressor assembly as in claim 1 , wherein the series of annular passageways comprise 4 annular passageways that repeat in a pattern axially about the bore of the baffle.
4. The suppressor assembly as in claim 3 , wherein each of the annular passageways are separated by a plurality of wall portions that reduce sequentially in thickness from the rearward end of the baffle.
5. The suppressor assembly as in claim 4 , wherein the front end cap is integrally formed with the baffle.
6. The suppressor assembly as in claim 1 , wherein the baffle is a monolithic structure and it is formed from a single monolithic piece.
7. In combination, a suppressor assembly and a firearm with a barrel, the suppressor assembly comprising:
a baffle having a concentric bore extending therethrough from a threaded opening and a series of annular passageways extending from the concentric bore to a tapered exterior surface of the baffle, the series of annular passageways being axially inclined rearward with respect to a rearward end of the baffle, wherein the baffle is in fluid communication with a muzzle end of the barrel;
a rear seal plate secured to a step feature of the barrel;
a housing; and
a front end cap, wherein the housing, the rear seal plate and the front end cap define an expansion chamber for receipt of expansion gases received from the baffle.
8. The combination of claim 7 , wherein the baffle is a monolithic structure and has a cone shape that increases in diameter as the baffle extends forwardly from the muzzle end of the barrel towards the front end cap.
9. The combination of claim 8 , wherein the series of annular passageways comprise 4 annular passageways that repeat in a pattern axially about the bore of the baffle.
10. The combination as in claim 9 , wherein each of the annular passageways are separated by a plurality of wall portions that reduce sequentially in thickness from a rearward end of the baffle.
11. The combination as in claim 7 , wherein each of the annular passageways are separated by a plurality of wall portions that reduce sequentially in thickness from a rearward end of the baffle.
12. The combination as in claim 7 , wherein the front end cap is integrally formed with the baffle.
13. The combination as in claim 7 , wherein the baffle is a monolithic structure and it is formed from a single monolithic piece.
14. The combination as in claim 7 , wherein the rear seal plate has a “U” shaped configuration that surrounds a central opening that is secured to the step feature of a barrel.
15. The combination as in claim 7 , wherein the rear seal plate has a ledge that is welded to the housing of the suppressor assembly.
16. A method for suppressing muzzle flash of a firearm, comprising:
directing combustion gases of the firearm rearwardly from a muzzle end of a barrel of the firearm into an expansion chamber located about the barrel through a baffle secured to the muzzle end of the barrel, wherein the baffle is a monolithic structure and has a cone shape that increases in diameter as the baffle extends forwardly towards a front end cap secured to the baffle and a housing that defines the expansion chamber and wherein the baffle has a concentric bore extending therethrough from a threaded opening and a series of annular passageways extending from the concentric bore to a tapered exterior surface of the baffle, the series of annular passageways being axially inclined rearward with respect to a rearward end of the baffle, wherein the front end cap is a separate unit fixedly attached to the housing.
