If a regular civilian wanted to purchase a Colt 6921 could they?
If so…
Could he/she avoid the SBR paperwork by having a Phantom/Smith V FS pinned and welded prior to taking actual possession?
OR
Could the purchaser take possession of the rifle and do the pin a weld themselves.
The SBR paperwork/laws is one thing I’m not up on.
What I would like to do is purchase a Colt LE6921 and avoid SBR paperwork by having a pinned and welded flash hider.
If it’s the “Colt” brand and 6921 look you are after, you could, as C4 suggested, purchase a 6920 and have the barrel cut and a phantom permed on, for 16" OAL and poof damn near a 6921. It would not be 14.5" but would look very short.
