Method and item for indentifying serialized parts
Serialized firearm parts, such as silencers, are identified using plates permanently affixed to the parts by welding, brazing, riveting, pinning and welding or other permanent techniques. Methods of effecting repair or replacement of silencers and silencer parts employ removing the plates by drilling or machining the welds and permanently affixing the plate to a replacement part.
1. A method, comprising:
inlaying a plate bearing an engraved serial number in a recessed portion of an outer surface of an essential part of a silencer, wherein an interior surface of the plate follows a first arc, wherein the outer surface of the essential part follows a second arc, and wherein the first arc and the second arc are concentric when the plate is inlaid on the recessed portion; and
permanently affixing the plate to the recessed portion.
2. The method of claim 1 , wherein permanently affixing the plate to the recessed portion comprises:
welding, brazing, riveting, or pinning and welding the plate to the recessed portion.
3. The method of claim 1 , further comprising:
after permanently affixing the plate to the recessed portion, attaching the essential part to a second part of the silencer.
4. The method of claim 1 ,
wherein an outer surface of the recessed portion follows a third arc substantially concentric with the second arc.
5. The method of claim 1 , further comprising:
forming the essential part and wherein a shape of the recessed portion is similar to a shape of the plate.
6. The method of claim 1 , wherein an outer surface of the plate follows a fourth arc that is concentric with the first arc and the second arc.
7. The method of claim 6 , wherein:
the outer surface of the plate is flush with the outer surface of the essential part.
8. The method of claim 1 , wherein an outer surface of the plate is flush with the outer surface of the essential part.
9. A silencer, comprising:
an essential part comprising an outer surface having a recessed portion; and
a plate bearing an engraved serial number, wherein the plate is inlaid and permanently affixed to the recessed portion, wherein an interior surface of the plate follows a first arc, and wherein the outer surface of the essential part follows a second arc that is substantially concentric with the first arc.
10. The silencer of claim 9 , wherein the essential part is an expansion chamber of the silencer.
11. The silencer of claim 9 , wherein the plate is welded or brazed to the essential part.
12. The silencer of claim 9 , wherein:
an outer surface of the recessed portion follows a third arc substantially concentric with the second arc.
13. The silencer of claim 2 , wherein:
an outer surface of the plate follows a fourth arc that is substantially concentric with the second arc.
14. The silencer of claim 9 , wherein an outer surface of the plate is substantially flush with the outer surface of the essential part.
15. The silencer of claim 9 , wherein the recessed portion and the plate have a polygonal shape or a rectangular shape.
16. The silencer of claim 9 , wherein the recessed portion extends around at least a portion of a circumference of the essential part of the silencer and the plate has a circular shape.
17. A method, comprising:
receiving an essential part of a silencer, wherein:
a plate bearing an engraved serial number is inlaid and permanently affixed to a recessed portion of an outer surface of the essential part,
an interior surface of the plate follows a first arc, and
the outer surface of the essential part follows a second arc that is concentric with the first arc;
removing the plate from the essential part; and
permanently affixing the plate to a replacement essential part.
18. The method of claim 17 , wherein the essential part is operably connected to one or more additional silencer components to form the silencer.
19. The method of claim 17 , further comprising:
releasing, after permanently affixing the plate to the replacement essential part, the replacement essential part; and
retaining, after releasing the replacement essential part, the essential part.
20. The method of claim 17 , wherein:
an outer surface of the recessed portion follows a third arc substantially concentric with the second arc.
