Firearms and accessories can just be about preference, not quality
Those arguments about which gun is better and which firearms optic is better is not much of an argument since Aimpoint, Eotech and Trijicon optics have all earned their way into the military durable optics. There have been some minor changes in these optics and we expect that all of the above mentioned companies will product new and better optics at some point in the future. Red dots are getting smaller and more precise and at some point in the near future there will be no battery usage in these optics and everything will be rechargeable or solar powered. Green reticles have outsold red reticles for the Trijicon ACOGS in 2012 and we don’t see that changing anytime soon.
The reality about the ACOG is that it is a fine medium range combat optic but there are always short comings in it’s usage. The TA01NSN is a fine ACOG that has built in iron sights for close range unlike optics like the Trijicon TA11H-G which is a DMR or SAW optics or even better a really good competition shooting optic. The Horse shoe reticle is a preference and for some people it works, others prefer the skinny and precise crosshairs that the TA01 ACOGS have. The TA11 has a much longer range reticle and hold overs with this optic are very accurate at 800-1000yds with correct ammunition.
