Imported Firearms and 922(r) Compliance

Three Main Scenarios

You're dealing with 922(r) in three main situations. First, if you're building from a parts kit--that Romanian AK kit needs U.S. compliance parts before you can legally assemble it. Second, if you're modifying an imported rifle by swapping furniture or components, you've just made yourself responsible for the parts count.

Third, if you're converting an imported pistol to an SBR, you're creating a rifle from foreign parts, which brings 922(r) into play.

The Good News About Retail Rifles

Here's the good news: if you bought your imported rifle at a gun store and left it stock, you're fine. The importer already handled compliance before it hit the shelf. Start changing parts? Now it becomes your problem.

Only 20 specific parts count toward your 922(r) total--not every screw and spring in your rifle. The ATF created a shopping list, and that's all you need to worry about.

The Official 20-Part List

Focus on What's Actually There

The parts you'll actually encounter on most builds include the receiver and barrel (usually foreign on imported rifles), trigger group components (which make easy compliance wins with U.S. triggers), stock components like the buttstock, pistol grip, and handguards, operating parts like the bolt, bolt carrier, and operating rod, plus muzzle devices if you've got a flash hider or compensator.

I've watched guys stress over every tiny component when only these 20 parts matter for compliance. Get the official ATF list, count what's actually installed on your specific rifle, and do the math. Don't overthink it.

You don't need to replace everything--just enough foreign parts to hit 10 or fewer total. Smart builders go after the cheap, easy swaps first and often improve the rifle in the process.

Smart Swapping Strategy

Typical Build Components

A typical compliance build might include a U.S. trigger group (covers multiple parts on the list and usually shoots better than the original), American furniture like stock, pistol grip, and handguards, a domestic muzzle device if you're adding one anyway, and a U.S. magazine if it's a fixed magazine design.

Most builds I see need $200-400 in compliance parts to get compliant, depending on what you're starting with. Don't cheap out on critical components like triggers--you're going to live with these parts, so buy once and cry once.

The legal reality: Converting imported pistols to SBRs appears to trigger 922(r) based on current ATF interpretation, even though pistols normally don't fall under this law. You're creating a rifle from imported parts, so compliance rules kick in.

Converting imported pistols to SBRs appears to trigger 922(r) based on current ATF interpretation, even though pistols normally don't fall under this law.

This catches a lot of people building Krink clones or other imported pistol conversions. Factor compliance parts into your SBR budget from day one, or you'll be scrambling to fix it later.

The feds wrote this law to control major assemblies, not to hassle people over springs and screws. Minor parts like pins, springs, screws, and small hardware don't appear on the regulated parts list, so they don't count toward your foreign total.

Also exempt are:

• Unmodified imports (stock WASR rifles remain compliant)
• Bolt-action rifles (only semiautos regulated)
• Sporting rifles (though definition can be complex)
• Any U.S.-made parts you install

Why Documentation Matters

Keep receipts for your U.S. compliance parts. The law doesn't specifically require documentation, but try explaining compliance without proof if ATF ever asks questions. I've seen too many "trust me, it's compliant" builds to recommend flying blind on this.

Buying from Reputable Sources

Buy from suppliers who actually mark their parts as 922(r) compliant and U.S.-made. Some foreign manufacturers stamp "Made in USA" on parts that definitely weren't, and that won't help you if push comes to shove.

922(r) sounds scarier than it actually is once you understand the 20-part list and can do basic math. But the penalties for getting it wrong make it worth taking seriously.

Count twice, buy U.S. parts from reputable suppliers, and keep your paperwork.
