If you're shooting sub-200 yards pretty much anything (including open sights) will serve you just fine. I routinely run the Eotech on my AR-15 out to 200 yards. We're training for hunting 6 ft tall bipedal targets in an urban environment, and a 0-200 yard distance works out well when zeroed for 50 yards.
But, honestly, if you're going to drop this optic on a Rem 700, I'd be inclined to suggest you pick up a decent variable power scope that would allow you to take the distances out further, should you ever get the chance to play in such a manner. I had a Weaver Grand Slam Tactical 3-10x scope on my precision rifle for a while, and it worked great for the $300 price I paid through Midway. I used that scope for shots between 25-650 yards on a regular basis.
Now, if you're throwing this optic onto an AR-15, I am a pretty satisfied Eotech customer. Again, my application is not a game hunting application, but the optic would probably serve me just fine for a coyote sized target inside of 200 yards. The reticle is quick to acquire, leaves you with a maximized field of view, and the optic is durable.
As you already mentioned, if you're shooting at those distances you certainly don't need a ton (or any magnification). But, again, I just figure a precision rifle deserves an optic designed for that type of mission!
