if you can afford it get the mark4….hands down the best of the ones listed..
i have a mark4 6.6×20 lighted tmr rectical and I like it better than my buddies nightforce nxs 22 power and I swear the optics are clearer in my mark4, maybe I'm a tad bias but oh well….i also have and older vx2 3x9x40 on my hunting rifle and it's a great scope for my set up…
