Throws the brass just like a std vz. No real diff there. Yes iron sights for now. I believe rausch is coming out with a side rail system for the vz. I'm waiting to see what it looks like before I buy any railed upper handguards or try to adapt an ak side mount to it.
But it will have a scope in the future, my eyes arent as good as they used to be! lol
About the only diff was it kicked a bit harder, but not much.
