Both eyes wide open - SIG SAUER Romeo4S Solar 1x20mm Compact Red Dot Sight w/Mount

This is second red dot, and my second Sig optic. I put this on a CMMG Banshee, and once I got it settled on the rail, it was incredibly easy to pick up with both eyes open. One thing I noticed was the challenge to adjust the point of aim. After making several elevation adjustments, I had to give it a wack with the buttplate of a magazine to get it to move. Once I got a zero, it held through hard use. Gread optic once again from Sig.
