Of course it will. Never mind accuracy, lets talk about reliability, servicability, comfort and the fact that I've never seen a speck of rust ever on any gun in the AR A-2 family.
Besides, who the hell wants a weapon that rattles when you pick it up? The mini sounds like a freakin' bucket of bolts.
I can only say that my two don't rattle. At least, if they do, I haven't noticed it.
