Im glad I jumped on it, its nice to catch a deal on some larue mounts, God knows I have spent enough with them in the last year alone! I didn't even need one but I got a 30mm anyway for later.

I agree, if you start out too tight, I'm sure it will leave a mark. When I mounted mine and made sure it was solid, I took it off because I was afraid it would mark the rail but it was fine. What I like about these is that you can remove it and put it back and it stays near zero. I don't believe there are a lot of options out there that will do that.
When you talk about return to zero are you talking about 1/4 or less at 25 yards or 1/4" at 100 yards. The later is my standard
