Firearm noise suppressor construction and method of manufacture and repairing
Provided is a firearm noise suppressor having a baffle chamber unit with at least one dimpled recess on an outer surface thereof. An identification band with identifying indicia thereon is placed on the baffle chamber unit over the at least one dimpled recess, and an area of the band is deformed into the dimpled recess to prevent the removal of the band without a machining process.
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 band 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 band being affixed to the outer surface of the baffle chamber unit so as to prevent the removal of the band without a machining process to the selected area.
2. A firearm noise suppressor, comprising:
a baffle chamber unit defining a plurality of interior chambers and having a length and an outer surface; and
a removable identification band with identifying indicia thereon assembled on the baffle chamber unit covering less that the entire length of the baffle chamber unit's length and a selected area of the band being affixed to the outer surface of the baffle chamber unit so as to prevent the removal of the band without a machining process to the selected area,
wherein the outer surface of the baffle chamber unit includes at least one dimpled recess, the identification band being situated over the at least one dimpled recess, and the band having a deformed selected area protruding into the dimpled recess.
3. The firearm noise suppressor of claim 2 , wherein the selected area of the band that is deformed does not include identifying indicia.
4. The firearm noise suppressor of claim 2 , further comprising corresponding threads on the outer surface of the baffle chamber unit adjacent the at least one dimpled recess and on an inside surface of the identification band.
5. The firearm noise suppressor of claim 2 , the outer surface of the baffle chamber unit comprising a plurality of dimpled recesses.
6. 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.
7. The firearm noise suppressor of claim 1 , wherein the indicia is engraved on an outer surface of the identification band.
8. The firearm noise suppressor of claim 1 , wherein the identification band is affixed to the baffle chamber units by welding only the selected area of the band to the baffle chamber unit.
9. A method of manufacturing a firearm noise suppressor, comprising the steps of:
providing 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;
providing a removable identification band with identifying indicia thereon and configured to fit on the baffle chamber unit to cover at least a portion but less than the entire length of the outer wall surface of the baffle chamber unit; and
placing the band on the baffle chamber unit and affixing a selected area of the band to the baffle chamber unit in a manner that prevents the removal of the band without a machining process to the selected area.
10. The method of claim 9 , wherein the selected area of the band that is affixed does not include identifying indicia.
11. A method of manufacturing a firearm noise suppressor, comprising the steps of:
providing a baffle chamber unit defining a plurality of interior chambers and having a length and an outer surface;
providing a removable identification band with identifying indicia thereon and configured to fit on the baffle chamber unit to cover less than the entire length of the baffle chamber unit; and
placing the band on the baffle chamber unit and affixing a selected area of the band to the baffle chamber unit in a manner that prevents the removal of the band without a machining process to the selected area,
wherein the baffle chamber unit has at least one dimpled recess on the outer surface and the band is placed over the at least one dimpled recess, the band being affixed by deforming the selected area of the band to protrude into the dimpled recess.
12. The method of claim 11 , wherein the selected area of the band that is deformed does not include identifying indicia.
13. The method of claim 11 , further comprising:
providing corresponding threads on the outer surface of the baffle chamber unit adjacent the at least one dimpled recess and on an inside surface of the identification band, and
threading the band onto the baffle chamber unit before deforming the selected area of the band into the dimpled recess.
14. The method of claim 13 , further comprising the addition of a thread-locking adhesive on at least one of the threaded surfaces before threading the band onto the baffle chamber unit.
15. The method of claim 11 , further comprising providing a plurality of dimpled recesses on the outer surface of the baffle chamber unit.
