I don't hear much about US optics anymore, not sure why. You may get some solid feedback from guys that use them on the snipers hide forum. I'm certain someone will be along shortly to tell you a vortex viper is just what you need! I don't have any really high end scopes I'm running NF ATACRs on a couple rifles and like them. If I do setup up to the next level S&B PMII will be the direction I head. Good luck on your search and welcome to the forum!
