The ATI top folding stock is plastic sort of copy of the Remington Police top folding stock. Check on the EQUIPMENT EXCHANGE on this site. Choate also makes a metal top folding stock. I have a Choate top folding stock and 3 Butler Creek side folding stocks, I prefer the side folding stocks. If you have to use a top folding stocked gun when folded you have no access to the sights and if you need to shoot you need to hit and that usually requires the sights to do it right. Also a lot of people on this site have made comments that the Remington top folder is uncomfortable to shoot with the stock folded out, it bites your cheek or something, I don't have one to compare. If I don't need it to fold ,I personally prefer the factory wood stock, but thats just me. ww w.milarm.com has links to Choate and also sometimes has folding stocks in stock ( just depends what make or model)
