I am not a "tactical" expert. First thought is that these are all quality manufactures, that have been around for some time, with great warranties. Scope quality across all manufacturers has really improved from 10 - 20 years ago. The only way to really decide is compare each scope side by side with the others. Judge clarity, reticule, and magnification against price. Don't be afraid to try others if the shop has them, i am sure others will suggest models and brands. Also you did not say the quality of the 223. I say this because the typical mistake is to put a cheap scope on a very good rifle. In the tactical world your choices may not be top money, but they are not cheap. Be sure to not go the other way and put a good scope on a poor rifle. Neither works well.
