On my .17 CZ Varmint I had to add a one inch cheek rise and when I mount, I’m dead on. I did not measure right the first time and called Michael and ordered a two piece to get me up to where I needed to be. I will have to do the same thing on the MTR and my Savage but will order a higher profile. It’s not very pretty but dead on. If you want to get a deal and terrific support check, out GODAGRIP on the web or you can call and talk directly to Michael directly. What a great guy and eager to help. Very reasonable prices.
