Imported Firearms and 922(r) Compliance

This article provides educational information only and is not legal advice. Consult a qualified attorney for specific legal questions.

Why it matters: If you're building from a parts kit, converting that imported pistol to an SBR, or swapping parts on your AK or imported rifle, you could be committing a federal felony without even knowing it. 922(r) catches more gun owners off-guard than almost any other federal law.

• The legal reality: Section 922(r) says you can't assemble a semiautomatic rifle or shotgun with more than 10 foreign-made parts from a specific list of 20 regulated components. It's Congress's way of preventing people from dodging import restrictions by bringing in "nonsporting" guns piece by piece.

The rule is straightforward—count your foreign parts, stay at 10 or under, or replace enough with U.S. parts to get compliant. But like most federal gun laws, the devil's in the details.

Who Gets Hit by This

What this means for you: Three situations put you squarely in 922(r) territory:

• Parts kit builders — That Romanian AK kit needs U.S. compliance parts before assembly
• Modifiers — Swapping furniture or components on imported rifles triggers the count
• Converters — Turning imported pistols into SBRs brings 922(r) into play

If you bought your imported rifle at a gun store and left it stock, you're fine. The importer already handled compliance. Start changing parts? Now it's your problem.

The Parts Count Game

Between the lines: Only 20 specific parts matter for 922(r)—not every screw and spring in your rifle. The feds created a shopping list, and that's all that counts.

• The big ones you'll actually deal with:
  • Receiver and barrel — Usually foreign on imported rifles
  • Trigger group parts — Easy compliance wins with U.S. triggers
  • Stock components — Buttstock, pistol grip, handguards
  • Operating parts — Bolt, bolt carrier, op rod
  • Muzzle devices — Flash hiders, compensators

I've seen guys stress about every tiny part when only these 20 matter. Get the official list, count what's actually on your gun, and do the math.

Getting Compliant Without Going Broke

What this means for you: You don't need to replace everything—just enough foreign parts to hit 10 or fewer. Smart builders target the cheap, easy swaps first.

• Common compliance strategy:
  • U.S. trigger group — Covers multiple parts, improves the rifle
  • American furniture — Stock, pistol grip, handguards
  • Domestic muzzle device — If you're adding one anyway
  • U.S. magazine — If it's a fixed mag design

I typically see $200-400 in parts get most builds compliant, depending on what you're starting with. Don't cheap out on critical components like triggers—buy once, cry once.

The SBR Conversion Trap

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.

• This catches a lot of folks building Krink clones or other imported pistol conversions. Factor compliance parts into your SBR budget from the start.

What Doesn't Count

Between the lines: The feds wrote this law to stop major assemblies, not harass people over springs and screws. Minor parts like pins, springs, screws, and small hardware don't appear on the regulated list.

• Also exempt:
  • Unmodified imports — Your stock WASR is fine as-is
  • Bolt guns — Only semiautomatics count
  • Sporting rifles — Though "sporting" gets weird fast
  • U.S.-made parts — Obviously don't count toward foreign total

Documentation Reality Check

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

The bottom line: 922(r) sounds scarier than it is once you understand the parts list and do basic math. But the penalties for getting it wrong—10 years federal prison—make it worth taking seriously. When in doubt, count twice and buy U.S. parts from reputable suppliers who actually mark their stuff as 922(r) compliant.

If you've built up a rifle from an imported parts kit, did you track which parts counted toward the 922(r) limit, or did you just swap things out as needed and hope you stayed compliant?
