Spuhr Mount 34 mm

Keep in mind your length of pull and setup. The one thing that bit me with Sphur mounts while they are amazing and a work of art is that if you want a short LOP where you put the butt pad in the crook of your elbow and have 90 degree trigger finger placement, they allow basically zero front/back scope adjustment in the rings on a Razor because the rings are so wide and closely spaced.

I just squeaked by on my AT at the very end of the rail, but on my TRG I had to add a 1/4" spacer into the stock and shoot a longer LOP than I wanted because I could not get the scope far enough forward in the standard Sphur mounts.

If I had it to do over I'd either do rings on a 20moa rail because you have so much more adjustment, or I'd have done the Sphur cantilever mounts.
 
Nope. Not visible and not needed anyways

Disagree. It is visible from the eye that's not looking through the scope. Just squint your sighting eye and the bubble comes into view. It can be used to double check you are holding true level, but yeah - not something I need to do much.
 
I just ordered the 4602 for my Tikka T3x TacA1. I need the 1.5" height. I needed 20 moa more to hit the mile steel without having to use my reticle for holdover. I was told it will have enough clearance for my 56mm Razor
