re: SCAR 17S. Talk me into or out of this purchase.

I looked at a SCAR 17S for a long time and eventually talked myself out of it. In January I ordered one of the new Rock River Arms X Series and it came in a couple months ago. To me, the RRA seemed like much more bang for your buck: stainless steel cryo barrel, two stage trigger, free floating hand rail, and probably more stuff I'm forgetting. At $1600 I have more money to spend on a scope at some point. However, I already own an AR and already having knowledge in the platform appealed to me.

I have the 4x ACOG on my AR-15. Awesome little scope and it's perfect for that gun. For a SHTF scope I think you'd be hard pressed to find a better one. Every time I look through the scope I'm impressed by how awesome it is.

I never considered an ACOG for my 308, I wanted the option to really shoot some tight groups at a medium range and I dont feel the ACOG is good for this. It's designed for quick target acquisition and to put bullets into a torso. It does this extremely well. But for a nice placed shot while hunting or if you want to blast bullseyes at 250 yards I think there may be better scopes than the ACOG. Take the ACOG comments with a grain of salt, just my opinion and the military guys can give better advice on them.
