I’ve got a 32” K32 Step Rib fixed choke 12ga.Barrel I’m not using. I purchased this a few years ago from gunbroker and never had it fitted to a receiver. The listing on GB stated it was a Bavarian Grade Barrel. I have no way to verify this but I can tell ya the blueing seems a lot deeper/richer than on my other k32 barrels. I do not have a way to check the choke constrictions but it’s supposedly IM bottom barrel Full on top. 2,000 and I’ll pay the ride. Thanks for viewing!
