Yes, I looked at the SFP model. I feel that optics over 10x benefit from FFP. This will be the route I go. If all my shooting was going to be from the bench at max magnification I'd go with the SFP option.

My goal is to get the most out of the 5.56/223 and then decide if the cost of going to a large frame ar is worth it. The Sierra TMK's give the 223 longer legs and make the decision tougher. Even paying the price for the TMK's is cheaper than 308. I thought about a Grendel, but feeding issues and bolt life are concerns. I don't want a wildcat. A MWS is a proven, reliable weapon that offers 308 and 6.5 creedmore. If I end up there, this scope will move to that rifle. It'd suck to end up underglassed again.
