I have one of these, and after a couple bad shoots have discovered that if I turn the ret locking screw on the side, (which is advertised as an extra feature to stop the scope shifting zero), I get a major point of impact shift, up and to the right.
So now I dont bother locking the ret off, and just leave it in the unlocked position, where it holds zero. I've not seen another scope use this feature, and I suspect it needs a bit more development
Just a heads up! Really nice scope otherwise, (if you like a very thin ret)
