Kris's Review of Trijicon TA31RCO-M4 ACOG 4x32 USMC M4 Rifle Scope w/ TA51 Mount &

As a former infantry Marine, I am quite familiar with this optic. The cost is steep but in my opinion, in the end, it is worth it. I have a handful of the other popular optics (EoTech) but, this is my favorite and the one I am most comfortable with. The fit and finish is high quality, which is typical of Trijicon.

Using this product is simple just mount, zero, and practice. This optic will reward you for many years with little more than basic cleaning. In my experience as a range officer, the easiest way to zero is shoot a paper target from ten yards (some systems came way off neutral) to ensure you will hit paper. From there I would use 25m BZO target. Ten rounds later you will have a workable 300 zero with 62 grain 5.56.
Best Used for:
