The problem here is that they don't have much time to devote to enforcement in general, but in specific cases they sure do.
Suppose you sell a gun to a trusted friend -- no problem, right? Well, suppose someone steals it from him and shoots the victim in a holdup. You can bet your bottom dollar that they will have plenty of time to trace that gun back to you and there will be dire consequences...

Chances are LE would go directly to the last known owner since they’d have no way of knowing of the transfer. Possible the thief will further incriminate himself, but I’d imagine criminal exposure for the transferees would depend on how savvy they are.
I have yet to see 'dire consequences' from a sale and a subsequent theft.
