I just shot my first match with my new SRO. It easily bests my RMR. The dot is easy to pick up, easy to track, and there is no goofy tinting. It is the dot to beat.
I haven’t seen an ACRO yet but I suspect it on,y beats the SRO in the closed optic format factor.
I have Aimpoints and a dot is a dot. The SrO glass is clear and big and the hood seems plenty sturdy for all but the most extreme abuse. It “suffers” from the same limitation of any projected dot. I don’t open carry nor duty carry so that is a meaningless issue to me.
If you like the RMR or the Deltapount Pro, you are going to love, love, love, the SRO. Love. No exaggeration. Everyone who handled it liked it.
