Hey all...Several years ago, I purchased a top folding stock made by advanced technologies for my mossberg 500. Although it looks nice, it is very impractical. It is difficult to shoot w/ the stock open due to the hard plastic that digs into my shoulder. However, when the stock is folded, the recoil flip forces the shoulder pad to flip up...Very, very stupid. I know there is a warranty, but I don't know what I can do to contact them. I can't seem to find their contact info...Any help?
