Using a Parts Kit
Get familiar with gun laws regarding parts kits. Commercial parts kits have all the hardware needed to make your own gun. Usually, the kits are for a semiautomatic, restricted non-sporting or fully automatic machine gun.
Typically, these parts kits are compiled from guns like AK-47s that have been deconstructed in demilitarized areas and legally imported as parts. To be legally acceptable, such a gun should be correctly redesigned. Essentially, the receiver has to be incapable of accepting the original fire-control components that are created to permit full automatic fire.
An acceptably redesigned semiautomatic copy of non-sporting firearm should be limited to using no more than ten of the imported parts. The parts list includes:
- Gas pistons
- Trigger housings
- Pistol grips
- Forearms, handguards
- Magazine bodies
- Frames, receivers, receiver castings, forgings, or castings
- Barrel extensions
- Mounting blocks (trunnions)
- Muzzle attachments
- Bolt carriers
- Operating rods
Get a parts kit of the type of gun you want to assemble. These can be somewhat hard found and you may not be comfortable buying such a package online. If you don’t know the location or source of the seller, use your judgment. You don’t want ATF agents coming to your door for buying illegal parts.
Consider going to a “build party.” It’s typical for gun enthusiasts to have build parties, sometimes making kits available to attendees for a good price. Usually held at gun clubs or private residences in many areas, build parties have all the hardware available to make your gun.
At a build party, you’ll probably have to sign a safety waiver and a non-disclosure agreement, making information about these types of get-togethers hard to come by. Your best bet is to go to your local gun retailer or gun event.
