I have an ASI Ultramax semi auto for sale. I have put a frew rounds with it and it ran through ammo with no issues. Barrel length is 20" and holds 4+1. They are a decent shotgun for the money. Has a couple of scratches on the frame but nothing serious, gun safe rash (bought it this way). Text with any questions. I meet in Buckeye only, no exceptions. I'll listen to an offer in person, tired of keyboard clowns.
