I had a Zeiss V6 30mm tube 50mm objective mounted with these rings on a 20 MOA Rail. Barrel is Proof Sendero Light.
I ended up 1/8 above the barrel with this set up.
Yeah, my rig will have 50mm obj and sendero proof, which may or may not clear, but I'm actually more concerned about bolt clearance with the magnification ring on my setup. I think there would be contact if I go that low...
Yes. I had that happen. Solved the problem by adding a 20 MOA rail.
I'm using a Defiance AnTi LA and for some reason they did not relieve the bolt handle to provide clearance for the magnification ring.
