So i just got a complete upper and tbh i dont know much about it. Has a keyhole mark on the reciever. Nothing on the handguard. The barrel has "6.5 grendel 1:8 SS" on it towards the end of the barrel. Anyway. My question how do i know what bcg to get for it. Is there a way i can determine type I from type II. Ive done some minor gunsmithing myself, but for ars i havent ever mounted a barrel. Dont just about everything else though. Ive got some calls out to local gunsmiths. One says he cant tell without having a bcg of either type. One more hasnt got back to me yet. Any suggestions?
