There is much to debate when it comes to low light fighting because as all debates, one change in the situation can alter the entire argument.   Recently I did some not so technical comparisons between some of the Trijicon ACOGS we had in the store and tested them out late at night.  I went from being in a well lit room to walking out into the night and see how the reticles looked.   One thing I did not like about the Trijicon ACOGS at first was going from bright sunny, well light reticle illumination to a dark room with a TA26SG-10.   I was not happy about the 90% change in illumination and for an instant I could not see the reticle when entering a room.

That is one argument I still use when boasting about my Eotech selection of combat sights.  The changes in illumination from the Trijicon Rifle Scopes that are meant for combat is something that you need to train for.   I also tested out the Trijicon TA01NSN to see how that worked in low light.   Once again I went from a well lit room with those nice dark black reticles to nighttime and the center most reticles began to glow.   What I did not like about this optic and reticle configuration was that even in low light, there is still light and the glowing reticle was not easy to see against street lights.   Another issue for reticles that have varying contrasts in different lighting.   If there was a way to regulate the changes in lighting that might make the Trijicon ACOG an even better optic.   Consistent lighting from an optic can mean something.  I am starting to like the Trijicon TA31F-G.
