Looking for some good advice from the operational pros out there... for a duty patrol rifle, M&P 15T with the free floating 16in barrel, I want an optic with some magnification though I still want to be able to access my BUIS if the SHTF and the optic becomes inoperable. I'm currently looking at the TA33R ACOG with the La Rue 105 mount, but I've also considered the benefits of a variable power Leupold MK4 1.5-5 with the illuminated reticle, and with La Rue mount/rings. I did not like the chevron reticle of my Trijicon tripower (just couldn't figure out the best way to get it zeroed... just above the tip? right behind the tip?) so I was thinking about the horseshoe reticle for the TA33 which I believe has a 2 MOA dot. I want to be able to do T-zone head shots at 100 yards. Obviously the Leupold will be a little more accurate with the 1/2 MOA dot and cross hair setup, but I want something that I can throw against the asphalt and still have it be zeroed. No batteries is also a plus. Any suggestions, ideas or experience with either/both sights would be appreciated. I've read a few small reviews on this site for both optics, but I think they were both a few years old. Just looking for some fresh feedback.
