Thanks for the input, aimpoint is the same we had when I was deployed, only one's I know much about, I will definately look into the other brands.
The trijicon is a bit on the pricy range. $1000+ for one, but well worth it. the eotech, depnding on which style are under $800. the 1 i have is 552 night vision compatible. it cost $550 from rockriver arms. it works flawlessly and didnt have any issues zeroing it, nor it staying zeroed.
