I’ve seen the trend towards the fancy pants combat optics with the 4×32 ACOGS with the red dots on top but then after people do enough shooting they find out that they didn’t need the magnification in the first place or the red dot optics are just mounted too dam high.   You can always adapt to the rifle but for house to house fighting having your head higher than need be is something of an annoyance.   People trended towards zero magnification optics like the Aimpoint or Eotech but then having zero magnification can be a problem in identifying threats.   There have been many second hand stories heard around our store of Law Enforcement not being to identify weapons from cell phones at distances of under 25yds.   Small  handguns can almost fit in the palm of your hand and there is a big difference between a cell phone and a Walther PPK.

Recently there has been a strong trend towards green reticles but the still very popular Trijicon reticle is the TA01NSN.   The Trijicon TA01NSN has a traditional crosshair style reticle but with bullet drop comp.   It is very important to know that combat style optics are more about speed than precision but precision accuracy is absolutely obtainable for even novice shooters because the optic is so well thought out.  Even though you have one of the toughest optics out there, the optic top is designed to have a low light engagement iron sight.  The rear sights have a wide aperture for close fighting not just as a backup if your primary sight goes down.  It is a very easy transition to go from optic to irons with this system.
