I have a few Mossberg 500’s and a 590. Over the years I have accumulated spare barrels, stocks, fore arms, etc. I had been looking for a cheap 500 for a project. Last week on GB on one of my favorite vendors that deals in police trade ins and confiscations a New Haven 600AST, by Mossberg, showed up. This is a Mossberg 500 that they made for Montgomery Wards and Western Auto. The AST meant rifles sights for slugs, in fact it was called “The Slugster” It had the original barrel but some one had put a pistol grip on it. I put a bid on it and won it for $116, cheap enough even counting shipping and transfer, I am in it for less than $150. Picked it up today, really not in bad shape except for some pitting on the barrel, I am changing that out any way. I will up date as I make modifications.
