Hey gang,
I am interested in getting the Faxion ARAK-21 upper for my build rifle. The cool thing about this upper is the barrels are interchangeable between 5.56 and 300 blackout. They offer a 12.5 inch barrel as well. all barrels have individual serial numbers.
My question is if I buy the upper with the 16" barrels and purchase the 12.5" separately, what part do I have to register with the ATF? The barrel or the entire rifle?
Thanks!
