I put one on a 308 PSS and it works fine..I also shoot with a guy that took off a Ken Farrel base off his gun and put a TPS on it and he said it works the same.
I will say it took them alot longer to get the base to me than I thought it would.
If money is not an option I would look at Glen Seekings bases. He is as good as they get! Welcome to Seekins Precision
