The only ideas I have are the side mount (which I'm not particularly fond of), and a scout type mount, and that'd only work for the right scope. Without the right scope, I think it'd throw the balance all out of whack. I want to use this rifle primarily for CAS, so I don't have to worry about a scope. I'm going to explore a tang sight and see how much it'll bug me, but I suspect that it'll get in the way more and bug me more than I'd really have a need for it.
But to answer your question, my only suggestions are a side mount or a scout mount.
Are you going to leave that safety intact, or have you given thought to ridding yourself of it like was suggested earlier by lostinvt?
