Ok gents, I discovered a new problem on my Choate Varminter stock. My Harris bipod when attached to the bipod rail on the stock, doesn't actually contact the stock. It only tightens up against the rail. This allows the bipod to move, a lot! So I tried mounting up my Blackhawk canting bipod, same problem. Tried a UTG bipod, and it fit like it's supposed to, it actually snugs up against the forehand of the stock. Both the Harris and the Blackhawk are about 3/16" shy of being able to tighten up against the stock. Has anyone ran into this problem before, or does anyone have good advise on how to remedy this concern? Thanks in advance, Mike.
