NFA Rules

*ALL NFA RULES APPLY. WARNING: 1. The addition of the H&K stock to a H&K type pistol with a barrel shorter than 16 inches in length results in the manufacturing of a short-barreled rifle (SBR) which falls within the classification of firearms subject to NFA controls [26 U.S. Code §5845(a)(3)]. Even if the pistol is not assembled into the butt stock, possession of the pistol and the butt stock would constitute a short barrel rifle (SBR) which may not be lawfully possessed unless it is registered to the possessor in the National Firearms Registration and Transfer Record in advance. 2. The Addition of the H&K stock to a H&K type pistol with a barrel of 16 inches in length or longer results in the manufacturing of a lawful sporting rifle. Prior to converting the pistol into a rifle, ensure you follow the guidance in 18 U.S. Code § 922 (r) and 27 CFR 478.39. It is YOUR responsibility to ensure that all laws and regulations are followed.
