I just ordered a Burris 135 red dot from Natchez, on sale for $99. My question is, what mount would you suggest to co-witness with my fixed front post? I've looked at the 1" burris high rise and the vortex cantilever. Any others I should consider? Not sure if I'll ever add a magnifier or not but I'm leaning towards the vortex to keep the option open. What say you?
