So if I understand this correctly my upper needs to be 14.5 with pinned welded flash to make it 16. Anything shorter I need to pay atf?
side note...SHotgun is 18"
Be careful though, not all flash hiders are long enough to make it 16".
side note...SHotgun is 18"
Now, let me say one more thing: you're better off with a 16" barrel than a 14.5" barrel with pinned FH from a ballistics point of view, and the length difference is pretty minimal. (Plus, extra-long FHs are fugly, but I suppose that's subjective.)
Get a bullpup...it is SBR short, maintains a full barrel and no taxtamps required.
