I have 4 Tikkas in Rokstoks now. They all land like this when fully seated down and torqued in at 65” lbs.I will need to do that tomorrow. I had already removed the stock thinking I might ship it back later today or first thing tomorrow morning. I did tinker with it and watched the lug (which is stamped UM), but I could not seem to get it to move in any way that made a difference. I will give it another try.
