Hi TooTallMall, I’ve got an old wingmaster I’m looking to part with. I’m not sure what you mean by EM but mines a 12g 28” improved barrel model. It’s a beautiful gun, that rings like a bell when your cycle a round. Does this fit what you’re looking for? If so, I was hoping to get a bit more then $300 l, but would discuss further if you absolutely can’t go any higher.
