I'm looking to find a gunsmith to give a quote on cutting down a 26" 20ga barrel to 20" or 22" and rethreaded for chokes. I've read lots of folks say not to since the stoeger barrels are chrome lined it may cause flaking in the lining as well as people saying I may not be able to have it rethreaded. Just curious as to if anyone has experience or can point me in the direction of some helpful knowledge and a quote.
