This is not a BATFE issue. All of the background checks are run through a FBI database. In some states, like Virginia, the call is made to the State Police who in turn run the check; in some like Florida, to other state agencies; and in others, directly to one (there is more than one database) of the databases for the background check. It is the same background check government contractor's run on potential employees who do not need a security clearance, but require a National Instant Criminal Background Check System (NICS).
A couple of web sites:
The barrel is one of the most important parts of a firearm, it is the metal tube that runs the entire length of the gun, and is used to guide the bullet from the magazine to the muzzle and fire it.The barrel of the Springfield M1903 rifle is manufactured using a cold forging process, to ensure that the barrel has a high degree of strength, durability and accuracy. The bolt is an important firearms component and is manufactured using the mim process.
I often make some gun parts, gun metal parts usually have some special properties, so they are usually made of special alloys, the manufacturing cycle of gun parts is very long, which is mainly limited by the level of craftsmanship, gun parts need to be precision machined and surface treated, some parts are made by MIM process to ensure their accuracy and reliability.
