Got a GAP with an AI stock. Yes, it is totally awesome more than I'd ever dreamed. Anyway I'm now looking at bi-pods. I'd like one that clicks into the end of the chasis but they are short legs, and I've heard they flop around alot. I'm gonna hunt sage brush with rolling bluffs and would really prefer longer legs. I'v seen some at the store with 23" legs but just wondering has anyone checked into this or suggestions with other websites. Thanks
