Any of you home gunsmiths have the tools for this that you would rent out? I've been wanting to thread my 590 for chokes (REM) for a while now because I don't want to buy another shotgun for interchangeable chokes. I think the 590A1 will last me a lifetime so why not modify it as I see fit? I know I can ship it off for around $100 and have it threaded, just thought that another outstanding member on here had already bought the reamer and die and would like to rent it out to get some return on their tools. I'd pay shipping, return shipping and your royalty in form of cash.
