Like it says - I'm looking for a 930 non-ported 24" 12G barrel threaded for chokes. There's a 2 year discussion on Eno's forum and some custom ones may have been made. I've done a good bit of searching but meeting all criteria has not happened yet. I can buy and modify but (of course) would prefer off the shelf. I'm looking to shoot 3gun this year and while small clubs might accept a defeated (covered) port - the letter of the rules push me into open classing. As a noob I may not care about classing BUT if there is an easy answer that I'm missing I'm going to certainly consider it. Thought I'd check here before calling Mossberg just in case! Thanks.
