18 U.S.C. 922(r), imposed in 1990, prohibits "assembling from imported parts any semi-automatic rifle or any shotgun which is identical to any rifle or shotgun prohibited from importation." BATFE`s regulation [178.39, Commerce in Firearms] prohibits using more than 10 "imported parts," from a list of 20 parts, such as trigger, hammer, barrel, etc. (BATF had proposed prohibiting using more than two imported parts.) The provision was adopted to prohibit restoring modified rifles to pre-law configuration after importation.
For further information please read Section 922(r), Title 18, Assembly of nonsporting semiautomatic rifles and shotguns in the Federal Firearms Regulation Reference Guide.
Below is a table that displays all the compliance parts and if they apply to Arsenal Inc. rifles.
