I have an original you can have for free, but I must caution you, they are a piece of garbage. The little thumbscrews will not support the legs extended for more than a few rounds fired. You should get a nearly identical version with click-stop notches that will hold elevation during use. Here is a link to an expired auction to show you what to look for: http://www.gunbroker.com/Auction/Vie...Item=194608537
I can still send you the mine, but you will not be happy with it.
