If your going with an acog, id suggest going with a 20 inch barrel because it'll be cheaper (vs a 14 inch barrel and all the taxes that come with) and you'll have to do less footwork, just find ammo that is 62 gr, and 3000 fps. If a shorter barrel is you ting, pay the taxes if you can and get the 14 1/2 inch barrel, again, less footwork. Any other lengths than that, either call trijicon or stick with your eotech.
With all that said I have the TA01NSN on my 16" M4 Forgery and I love it I am not concerned about the stadia lines not matching perfectly because I am not engaging towel heads out to 600 meters.The TA01, TA11, & TA31 (.223) were designed for the 5.56mm, 20 inch barrel, 55 grain bullet, and M16/AR15 carry handle mount. The TA01B & TA11C(.308) were designed for the 7.62mm, 20 inch barrel, 168 grain bullet, and M16/AR15 carry handle mount. The TA01NSN was designed specifically for the US Special Operations Command SOPMOD M4 Carbine. To meet their requirements, the reticle bullet drop compensator and range finding stadia lines were based on the trajectory of the 62 grain bullet from a 14.5 inch barrel, flattop mount (Picatinny rail Mil.Std.1913).
