922(r) Compliance Calculator

posted Friday, June 12th 2015 at 10:16 AM by

There are a few 922(r) compliance worksheets floating around on the internet, most are really good but quite a few are dated, not functional, and as I discovered when I started my Galil build, inaccurate. I wanted to provide a more up to date resource, and here it is!

Just click on the firearm you'd like to work on, and tick the appropriate checkboxes. If you spot an error or would like to see a new firearm added, please contact me. More information on the 922(r) law is below.

What is 922(r)?

Part of federal law is the United States Code, and Title 18 includes a section listing prohibited acts. Section 922(r) is the law making it illegal to assemble a firearm that is banned from importation. Here is the full text of the law from 18 U.S. Code § 922(r):

18 U.S. Code § 922 - Unlawful acts

  • (r) It shall be unlawful for any person to assemble from imported parts any semiautomatic rifle or any shotgun which is identical to any rifle or shotgun prohibited from importation under section 925 (d)(3) of this chapter as not being particularly suitable for or readily adaptable to sporting purposes except that this subsection shall not apply to—
    • (1) the assembly of any such rifle or shotgun for sale or distribution by a licensed manufacturer to the United States or any department or agency thereof or to any State or any department, agency, or political subdivision thereof; or
    • (2) the assembly of any such rifle or shotgun for the purposes of testing or experimentation authorized by the Attorney General.

How Does 922(r) Apply to Firearms

922(r) itself states that its illegal to assemble a rifle that's banned from importation. However, if a sufficient number of parts are made in America, the rifle is considered American made and not in violation of 922(r). The specific list of parts that are regulated is clarified in 27 CFR § 178.39 - Assembly of semiautomatic rifles or shotguns. Here is the full text of the law, which contains the list of qualifying parts:

  • (c) For purposes of this section, the term imported parts are:
    • (1) Frames, receivers, receiver castings, forgings or stampings
    • (2) Barrels
    • (3) Barrel extensions
    • (4) Mounting blocks (trunions)
    • (5) Muzzle attachments
    • (6) Bolts
    • (7) Bolt carriers
    • (8) Operating rods
    • (9) Gas pistons
    • (10) Trigger housings
    • (11) Triggers
    • (12) Hammers
    • (13) Sears
    • (14) Disconnectors
    • (15) Buttstocks
    • (16) Pistol grips
    • (17) Forearms, handguards
    • (18) Magazine bodies
    • (19) Followers
    • (20) Floorplates

    Hiya! I know this is kinda off topic nevertheless I'd figured I'd ask. Would you be interested in trading links or maybe guest writing a blog post or vice-versa? My site discusses a lot of the same topics as yours and I feel we could greatly benefit from each other. If you might be interested feel free to shoot me an email. I look forward to hearing from you! Superb blog by the way!
