I zeroed the Acro on the Rattler today, worked great. The big surprise was how well it worked with a magnifier. I was using an Eotech 3x to help with a zero at 50 yards. The dot looked awesome through the magnifier, better than the Eotech EXPS and Holosun AEMS I also used the magnifier with. I shot steel to 300 with the Rattler.
