We just finally received this tool that I first saw at the last Shot Show (2020). These have been on back order for several months and we just received a small shipment from Real Avid. In my opinion this is the best and easiest reticle leveler I have ever found and will be using it from now on when we mount customers (and our own) scopes. It levels the reticle and not the turret as more often than you would think the reticle is not square with the body and turrets even in higher end optics. $89. Phil.
