Leupold Mark AR Mod1 on my 716
I am in a much different budget than when I first started shooting. Now I first would look for an ACOG in anything I was using for 200+ shots, but they are a luxury item which I have drifted towards.Vortex makes nice stuff. I have no need for a piece of glass with that capability, though. I have my eye on the Spitfire 3x., but having the money I would look at a Trijicon ACOG variant, but your budget precludes that. I think the SF3 would be a nice piece of glass out to say 100 yards. Beyond that you may want a bolt .308?

UPDATE: Sorry, I overlooked the "7" in your 716...was thinking strictly AR15 when I read patrol rifle. I like the Strike Eagle...should get it done nicely, IMHO.
