Let us know how that turns out. I've been getting pretty interested in that unit myself, probably going to pull the trigger on one once finances improve. Only potential issue I see is the stock angle might not allow for a great sight picture with optics, but a cheek pad of some sort might straighten that out.
* SFRC's regular price on that particular item is already way better than anything I've seen local! Plus the sale! Damn wish I had some cash kicking around, time to find some side jobs....
