Again, thanks for the info guys, I really appreciate it. Now I hope my scope fits without issue. I'm planning to mount a Sightron S2 Big Sky, 3-9x42 with the Talley low rings. If Sightron and Talley state accurate dimensions, the objective end of my scope has a diameter of 1.99", the Talley rings are supposed to measure .400" from the top of my receiver to the bottom of the inside of the rings.
The scope tube diameter divided by 2 = .5", the objective diameter divided by 2 = .995", and the distance from the top of receiver to the inside bottom of either ring is .4", so clearance between the bottom of the objective and the top of the receiver = (.995 - .5) - .4, or .095". My Mark 11 has a heavy barrel, which measures .062" below the top of the receiver, so on paper I should have a total clearance of .157" from the top of the barrel to the bottom of the objective end of the scope. Maybe I should measure my scope to see how close Sightron's published dimensions are.
I really need to measure the thickness of the scope cap to see if it's going to fit after the scope's mounted
Oh well, if it doesn't fit, that might be a good excuse to try out one of the Vortex Viper 2-7x32's
