308 AR's are getting improvements. Dual ejectors, reduced weight in various parts of the gun components, cross compatibility with more 5.56 parts, more aftermarket options (barrels, magazines, etc). If they end up being only 30% more than their 5.56 brothers the SCAR17 will have more competition for the budget precision optic shooters. Not to give you buyers remorse before you even get your SCAR (bc I still want one as well) is the SCAR 17 worth 2-3 times the extra cost of a AR308 with all the new developments they've made/going to make.
