Or a dremel and cut the front sight off, then use a clamp-on style. Armalite (carried by Wolverine) has the clamp-on A2 style - which aside from the lack of bayo lug - looks exactly like a regular forged A2.
The problem is the Chinese made AR clones usually have such a heavily attached taper pin set, that it's very difficult to remove them. I've seen some that are mushroomed on both ends, making it impossible to get off without grinding them flush first.
