Well mounted it on my AR-15 with out use of a scope rise. Using Warne tactile 30 MM rings had to mount the scope as absolutly far forward as it could possible go for comfortable eye relief. I think its a keeper no doubt about it. Clear picture ,side focus nice and smooth . Its going to work out very well. I can't afford a NXS or IOR, US Optics. My use will be for coyote hunting and varmints.
