I've been researching the snot out of this topic. My range and most ranges in my area only go out to 600 yds. Without getting specific on my end here's what I learned this past year. I may be wrong on some thoughts, if I were certain a purchase would have been made on my end. Primary Arms makes a decent scope with good glass. Their warranty/guarantee is lacking in real time. Can't go wrong with Leupold. US Optics, Night Force, and Schmidt & Bender are the big three with top notch equipment. Kahles is on top as well. Burris and blank ( I'll fill that name in when 2nd coffee hits) have been names in the industry for many years and have a rep for lower end scopes, but they make excellent high end scopes, don't let the names fool ya!
I haven't made a purchase for myself as I'm still thinking I can buy one and not buy a second scope. Probably end up with three. I have bought a couple of red dots but gave them away as gifts. Holosun green dot is a well made piece of gear and not the highest priced either--- nephew received that one. Gotta walk the pup, I'll be watching this thread, I really need help finally deciding on a scope for me.
