Key Provisions
  • Prohibits assembly of semiautomatic rifles or shotguns using more than 10 foreign-made parts from a list of 20 regulated components
  • Applies to parts kit builders, those modifying imported firearms, and converters turning imported pistols into short-barreled rifles (SBRs)
  • Only 20 specific parts count toward the foreign parts limit: receiver, barrel, trigger group components, stock components, operating parts, and muzzle devices
  • Imported firearms sold stock from gun stores are already compliant; compliance becomes owner's responsibility when parts are modified or replaced
  • Converting imported pistols to SBRs triggers 922(r) compliance requirements per ATF interpretation
  • Compliance achieved by replacing foreign parts with U.S.-made parts to maintain 10 or fewer foreign regulated components
  • Exempts bolt-action rifles, unmodified imports, and minor components like pins, springs, and screws not on the regulated parts list
Applicability
Applies ToIndividuals assembling or modifying semiautomatic rifles or shotguns using imported parts, including parts kit builders and those converting imported pistols to rifles
Exemptions
  • Unmodified imported firearms sold in compliant configuration
  • Bolt-action rifles (only semiautomatic firearms covered)
  • U.S.-made parts
  • Minor components not on the 20-part regulated list (pins, springs, screws, small hardware)
  • Sporting rifles (though definition is subject to interpretation)

Imported Firearms and 922(r) Compliance

Legal information and analysis

From The Boise Gun Club Handbook

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

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 trap: Section 922(r) says you can't assemble a semiautomatic rifle or shotgun with more than 10 foreign parts from a specific list of 20 regulated components
  • The reason: Congress wanted to prevent people from dodging import restrictions by bringing in "nonsporting" guns piece by piece
  • The reality: Penalties go up to 10 years federal prison for what amounts to a parts-counting mistake

The rule sounds simple--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, it's the details that'll bite you.

Who This Actually Affectsedit

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.

The Parts List That Actually Mattersedit

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
Part CategorySpecific ComponentsCompliance Notes
Core ComponentsReceiver, BarrelUsually foreign on imports
Trigger GroupTrigger, Hammer, Sear, DisconnectorEasy compliance wins
FurnitureButtstock, Pistol Grip, HandguardsCheap to replace
Operating PartsBolt, Bolt Carrier, Operating RodCritical function components
AccessoriesMuzzle Device, Flash HiderIf installed
FeedingMagazine (fixed designs)Varies by rifle type
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.

Getting Compliant Without Breaking the Bankedit

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.

Timeline for typical 922(r) compliance build

Smart Swapping Strategy
Compliance StrategyParts Count ReductionTypical CostBenefits
U.S. Trigger Group3-4 parts$100-200Better performance
Furniture Set3 parts$75-150Customization options
Muzzle Device1 part$25-75Improved shooting
U.S. Magazine1 part$20-40Additional capacity
Complete Package8-10 parts$200-400Full compliance
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 SBR Conversion Issueedit

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.

What Doesn't Countedit

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

Documentation and Proofedit

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.
