What’s the Law: Barrel Extensions



Topic: Barrel Extensions

Question: I have rifle with a barrel under 16”; however, the barrel has a flash suppressor that makes it over 16”. Is this still legal?

Answer: If your barrel extension is attached by pin and weld it may be illegal under the NFA law as of April 2009. It must be full fusion welded or pinned with the pin head welded over.

Sections 2.1.1 and 2.1.3 are the sections of interest; section 2.1.3 states:

Acceptable methods for permanently attaching a device to a barrel are deep penetrating, full fusion, gas or electric
