## Abstract

Provided is a firearm noise suppressor having a baffle chamber unit defining a plurality of separated interior chambers and having a length and a substantially imperforate outer wall surface. The interior chambers are separated by at least one interior baffle wall with a central opening configured to allow passage of a projectile. A removable identification member with identifying indicia thereon assembled on the baffle chamber unit covers at least a portion but less that the entire length of the outer wall surface of the baffle chamber unit's length and a selected area of the member is affixed to the outer surface of the baffle chamber unit so as to prevent the removal of the member without a machining process to the selected area.

## Claims

### Claim 1

A firearm noise suppressor, comprising:
a baffle chamber unit defining a plurality of separated interior chambers and having a length and a substantially imperforate outer wall surface, the interior chambers separated by at least one interior baffle wall with a central opening configured to allow passage of a projectile; and
a removable identification member with identifying indicia thereon assembled on the baffle chamber unit covering at least a portion but less that the entire length of the outer wall surface of the baffle chamber unit's length and a selected area of the member being affixed to the outer surface of the baffle chamber unit so as to prevent the removal of the member without a machining process to the selected area.

### Claim 2 (depends on 1)

The firearm noise suppressor of claim 1, wherein the indicia is engraved on an outer surface of the identification member.

### Claim 3 (depends on 1)

The firearm noise suppressor of claim 1, wherein the baffle chamber unit comprises a series of baffle parts joined together without a separate outside tubular housing.

### Claim 4 (depends on 1)

The firearm noise suppressor of claim 1, wherein the identification member is affixed to the baffle chamber units by welding only the selected area of the member to the baffle chamber unit.
