ACOG is in my opinion, the undisputed leader in battle rifle optics. The designs are very well executed and have in many cases not only revolutionized the imaging field but also set the standard. The TA648-308 was chosen by the British as their primary battle ready modular weapons sniping optics over all other available options regardless of cost. Clearly the ACOG648 is not a scope in the usual sense however, it addressed effectively the requirements to quickly, and accurately acquire targets at a distance in battle conditions, effectively. The one significant drawback is the weight, not the size, although it is a monster. I have many weapons and sights and would still recommend this choice of riflescope over any other if the criteria is to effectively, accurately and easily engage targets with precision at considerable distances under battlefield conditions. Otherwise choose a more traditional riflescope. This is a very unique, costly piece.
Pros: Excellent optical imaging, target acquisition, magnification.
Cons: Heavy, heavy, heavy.
