For now.
If the FPC (see also here) and SAF (see also here) have their way, then eventually the price of a Thompson clone could drop to a few hundred present day dollars.
In related news, I didn’t realize people were working on the interstate sale problem. I think should be an easy win. I’m pleased to see it is being addressed.
And much more useful. Then, and more so today.
You want that riot problem to go?
While I would like to see a full auto Thompson available for less than $1K it would simply be as a middle finger to all the gun grabbers. As nice as they were a century ago there are much better and more suitable choices available today.
