I shoot my MR762 to 1100 yards, and ive had 3 optics on it already with a 4th on the way. Currently its scope-less as my Nightforce 4-16x44 ATACR FFP is about 90 days out, but that will be the scope that stays on it as I can engage just about anything within reason. Prior to that, I had a Nightforce 2.5-10x32 that was also fantastic, but it just didn't allow for me to print nice little groups at 100 like I wanted to when I was doing my hand load development. After that was a Steiner 3-12x50 scope that was pretty much perfect other than the actual size of the scope, which the NF is now smaller with more magnification, however I could do anything with the 3-12, and also had a Leupold Mark 6 1-6, which is now on my Scar 17 SBR instead. Choose the scope that best fits your interests and actually suits your NEEDS, not necessarily your WANTS, unless you just want a show gun to sit on your desk and send pictures to friends. I have at least one of my rifles out once a week either doing load development for groups, and then hitting steel at extreme distances. The odds of me doing anything requiring the gun to fall off a cliff, enter battle under fire, or blend in with the environment are non existent, but I still trust Nightforce as not only the best built scope, but the best quality for the money with the ATACR series HD glass rivaling S&B (obviously opinions may differ), and durability being second to none with the best mechanics of all the scopes. The downside about a scope that durable (any of the higher end glass) is weight. If its a bipod gun, or a "for looks" gun to appreciate, then weight doesn't matter, but I have to hump my rifle in 1/2 mile to get to my spot, so some of the more durable scopes such as the Vortex Razor line, weighing in at near 3 lbs, were out of the question.
My LWRC REPR is wearing a Nightforce 5.25x56 ATACR scope and while the glass is absolutely amazing, its too large of a scope for a 16 inch 308 AR unless you want to pick the button at long distances you plan on hitting. Your eyes may vary, but I have no issue hitting a 16x20 torso at 1100 yards with a 10x scope so it sounds like for your setup, a 2.5-10x32 Nightforce (or 2.5-10x44 if you want more light), or a 3-18x44 Leupold Mark 6, which while lighter will also be less durable, or on the lesser price end, the Vortex PST 2.5-10x32 FFP is a FANTASTIC scope for half the price of the others. It may not take a 15 foot fall, but vortex will give you a new one regardless of the damage. Im personally a fan of the smaller objectives for a 16 inch gun though... if you want my vote on an all purpose 50-1000 yard capable scope, get the NF ATACR. Might be able to score a lightly used one on Snipers Hide if you don't want to pay new prices.

alternatively if youre never going to shoot past 500 yards, look at the Vortex Razor 1-6, its one of the highest regarded mid range optics available... great price, the best warranty, incredible glass, and has a bright red dot for 1x, and FFP reticle for 6x. I have the Leupold and its nice being a bit lighter, but also near twice the price.
