Cummins, we have the 4-16 available in SFP in the X1000 line. The FX1000 is all FFP. The windage isn't capped because this scope isn't $2k+. We could have done in but it would require an entire new scope chassis and that would have doubled the price of the scope. We will have a lot more to offer in the future but were trying to bring the most scope for the money of anyone.
