Going to buy the "final" part for my Ar15 build (the bcg) after that It will be in working order. According to the note I received with the lower's registration certificate I must call them when the rifle can be fired.
What info do they require upon notification? I would assume calibre, barrel length and OAL. Just want a heads up so I can have everything ready when I make the call.
Also due to the modular nature of the Ar15 can more than one upper be registered to an individual lower? I am toying around with the idea of doing a 6.5 with a heavier barrel.
