If one buys a .20 MOA one piece mount such as those in development by Third Eye Tactical, I take it that you no longer need a Picatinny Rail as the one piece mount goes on the top of the receiver?

Are one piece better than two piece?

Yes the TET rail replaces the standard rail, I prefer one piece as they add a little bit more rigidity to the receiver, Also two piece mounts *might* move relative to each other which will never happen with a one piece mount.
