## Abstract

A one-piece sleeve which envelops a chamber with a baffle in a firearm suppressor body is disclosed. The one-piece sleeve has an elongate opening, or slot, extending longitudinally along all, or part of, the length of the sleeve. This way, because of the slot, the sleeve has increased flexibility and may be easily slightly opened up, and more easily removed from the elongate suppressor body for cleaning.

## Claims

### Claim 1

A firearm noise suppressor, comprising:
an outer, hollow shell for attachment to the muzzle of a firearm;
a chamber within said outer shell, the chamber having a plurality of separate, individual baffles, the assembly of the outside perimeters of said baffles being an elongate body;
the chamber and baffles also being within a hollow inner sleeve, the inner sleeve fitting between the elongate body and the inside perimeter of the outer shell, the inner sleeve being adapted to be supported by a friction fit with the elongate body, and the inner sleeve being one-piece and having a longitudinal slot so that the inner sleeve has increased flexibility.

### Claim 2 (depends on 1)

The suppressor of claim 1 wherein the outer shell is generally cylindrical.

### Claim 3 (depends on 1)

The suppressor of claim 1 wherein the inner sleeve is generally cylindrical.

### Claim 4 (depends on 1)

The suppressor of claim 1 wherein both the outer shell and the inner sleeve are cylindrical.

### Claim 5 (depends on 1)

The suppressor of claim 1 wherein the elongate body has a radially outwardly extending pin.

### Claim 6 (depends on 5)

The suppressor of claim 5 wherein the outwardly extending pin is adapted to fit within the longitudinal slot of the inner sleeve.

### Claim 7 (depends on 6)

The suppressor of claim 6 wherein the pin extends past the longitudinal slot to abut with the inner surface of the outer shell.

### Claim 8

A firearm noise suppressor, comprising:
a hollow suppressor structure for attachment to the muzzle of a firearm;
a chamber within said hollow suppressor structure, the chamber having a plurality of separate, individual baffles, the assembly of the outside perimeters of said baffles being an elongate body;
the chamber and baffles being within a hollow sleeve, the sleeve friction fitting around and being supported by the elongate body, the sleeve being one-piece and having a longitudinal slot so that the sleeve has increased flexibility.
