I know this is a long shot, but figured this was the area most appropriate for my question.

I'm creating a replica Thompson M1A1 (semi-auto). I have my Form 1 tax stamp for the creation of the SBR, I have my receiver engraved, but I'm stuck with the long barrel still on the receiver and no way to remove it myself.

Auto Ordnance sells SBRs directly but will not remove a rifle length barrel and install a short barrel after sale. I can't really blame them. Who wants to go through the entire Form 4 transfer process to take possession, perform the work for relatively little profit, and then go through another Form 4 to transfer it back?

There used to be a tool kit available for barrel removal on Thompsons, but it appears to be at least a decade out of availability now. More details here...

I could try to make something similar, and/or sacrifice the original rifle length barrel -- which I have no further use for anyway -- while removing it, but I don't want to damage the M1A1 barrel while installing it, obviously.

I thought maybe someone here might have an idea on how to proceed with this. Full disclosure: I've never removed a rifle barrel in my life.

Thanks in advance!

For further reference, here's a video of a Thompson barrel removal using the now-unavailable tool kit...

You need a special set of tools to do it properly which are hard to find and expensive. Can probably get one of the smiths there to do it a lot cheaper

That tool doesn't look too difficult to make?

Thanks, I'll give it a shot. Most of the posts on those groups are WAY out of date, though.
