I have been shopping around for a project gun. I found one locally, well 30 miles from me. it's an old 12 ga Wingmaster with a 28" barrel the stock has some deep gouges. Bluing in worn in places. The guy wants 200 bucks. I was thinking of offering 150 bucks. I'm trying to keep the cost down as i will be replacing the barrel with an 18". Do you think 150 is too low an offer?
