Recently I got into bow hunting and some of the bows they have out now are setup just like rifles are.   The optics are as fancy as the stuff that Trijicon has out and I got a good crash course on green vs red reticles.   Illumination is something that can bother me.   I still have pretty good eyesight for my age and I really don’t like it when I have reticles that obscure my target or cause fuzz and  haze.   Many of the red dot optics just piss me off if I have to use them past 100yds.  I do like my Eotech optics but am still looking for those skinny reticles.
The Trijicon TA01NSN is my favorite Trijicon ACOG and it is because it has nice skinny black lines and backup iron sights.   The TA01 is the even simpliar version of the ACOG.   These Trijicon Rifle Scopes have illumination when it is dark out but the bad thing about them is those nice thin black lines get lost on black clothing targets.   How many bad guys wear black over in Iraq and Afghanistan?  The vast majority of them.  Not only can a red dot obscure your target your black lines will fade on a target too.   A little bit of color contrast is a good thing for hunting and defense.
