If you want a good scope that I find and personally like far better than any leupold I've ever shot for about 1/3 the price and is every bit as accurate and reliable go with the Millett TRS line of scopes, TRS2 is fixed power, TRS1 is adjustable 4-16x50 with 30mm tube and iluminated mil-dot reticle. I've shot this many times accurately at 500 yds on my DPMS LR-308. Holds zero very well with the higher powered shell, built like a brick shithouse, good clarity, and can be had new for about $300 roughly (probably about $280 on ebay)
