Nope. Don't do it!
That would violate the import ban. Taking a gun that was imported after being deemed "suitable for sporting purposes" and changing it into another configuration is illegal. The only way around it is to make it a "US-made rifle" by swapping out enough parts that there are no more than 10 foreign made parts left out of the following list:
"Receivers, Barrels, Muzzle attachments, Barrel Extensions, Gas Pistons, Forearm Hand Guards, Trigger housings, Disconnectors, Magazine bodies, Magazine Followers, Magazine Floor Plates, Bolt carriers, Bolts, Hammers, Triggers, Sears, Butt stocks, Mounting blocks, Operating Rods, and Pistol Grips"
The trick will be getting US-made furniture, trigger assemblies and trigger parts. Switching one foreign part out for another doesn't help you unless the rifle already has enough US parts that the switch doesn't matter.
Hope that helps!
Some of the Vector's Semi-Auto Uzi Receivers are domestically made. The import ban does not apply to those.
