And being that you want it down to 12.5, I dont think NRW has even come out w/that data yet for a 12.5 switch block. Even if you could convince them to share it with you, if they dont have it, we are SOL. So unless you know for 100% certainty what size you need that gas port resized, what size the switch block regulates at each setting, and how much gas that specific 12.5 bbl needs to run, I'd avoid it.
I'd ditch the barrel on the EE, and contact Wes @ MSTN. I know for a fact he has some 10.5 N4 bbls w/switch blocks in stock..
I'd hate to see you end up with a bbl that you'd have to ditch the switch block completely on...
