This invention relates to firearms, and serialized parts such as silencers.
The Gun Control Act of 1968 requires that all firearms manufactured or imported into the US bear a serial number. The serial number must be conspicuously engraved, cast or stamped on the firearm frame or receiver. Previously, the National Firearms Act of 1934 defined categories of regulated firearms. In this classification scheme, silencers were defined as Title II weapons (along with machine guns), and are thus subject to an expensive stamp tax and required to bear a serial number even though not a firearm. Silencers and machine guns are most heavily regulated. In fact, the components of a silencer are considered as “silencers” by themselves and the replacement parts are regulated. However, the repair of original parts without replacement can be done by the original manufacturer, an FFL (Federal Firearms License) gunsmith, or by the registered owner without being subjected to new registration as long as the serial number and the caliber are maintained. The length of a silencer may be reduced in repair, but cannot be increased. Increasing the length is considered as making a new silencer.
Silencers are subject to considerable wear in their use. Multiple cycles of high internal pressure, projectile strikes on baffles and high gas temperature all take their toll and may require repair or replacement of silencer parts to maintain optimum performance. Furthermore, it may be desirable to change the length of a silencer for a particular need, for example to reduce weight and length. The laws governing silencers however, make repair and replacement a costly and time consuming process. There is clearly an opportunity to improve the ability to repair or replace silencers while still operating safely and within the law.
The invention further encompasses a method of identifying a serialized part such as a silencer. In an example embodiment, the method comprises permanently affixing a serialized plate 10 bearing a serial number 12 to the part 14. Permanently affixing the plate 10 may comprise welding, brazing, riveting or pinning and welding the serialized plate 10 to the part 14 as described above for
Also encompassed by the invention is a method of effecting repair of an essential part of a silencer. An example part 14 (silencer 16) is shown in
A further example method of effecting repair of an essential part of a silencer method may comprise:
Regardless of whether the example repair method requires release of the silencer, including the serialized plate to a manufacturer or a holder of a Federal Firearms License, various steps of the method are common. For example, the step of removing the serialized plate may comprise drilling or machining out welds permanently attaching the serialized plate to the original essential part. Permanently affixing the serialized plate to the essential replacement part may comprise welding, brazing, riveting or pinning and welding the serialized plate to the replacement essential part. When the serialized part comprises a silencer, the essential replacement part may be shorter than the original essential part, or the replacement essential part may be a different caliber from the original essential part. When the method requires release of the silencer, including the serialized plate to a manufacturer, the manufacturer may be the original manufacturer of the silencer, or another manufacturer of similar parts.
The invention also includes methods of replacing an essential part of a silencer. One example method comprises:
Another example method of replacing an essential part comprises:
Regardless of whether the example replacement method requires release of the serialized part to a manufacturer or a holder of a Federal Firearms License, various steps of the method are common. For example, the step of removing the serialized plate may comprise drilling or machining out welds permanently attaching the serialized plate to the original essential part. Permanently affixing the serialized plate to the essential replacement part may comprise welding, brazing, riveting or pinning and welding the plate to the serialized replacement part. For a serialized silencer, the essential replacement part may be shorter than the original essential part, or the replacement essential part may be a different caliber from the original essential part. When the method requires release of the silencer, including the serialized plate to a holder of a Federal Firearms License, the holder may be the original holder from which the silencer was purchased, or another holder of a Federal Firearms license.
