AK 74 chambered for 6 MM ARC?

[stanc]

In an AK-74 the 6 ARC might not be much more difficult to control in full auto than the 5.45x39.  The 6 ARC looks to have several advantages in an AK-74, no decrease in ammo capacity, flatter shooting with higher energy on target.  With the Russians using more optics and having graduated iron sights the 6 MM ARC could increase the effective range of the AK-74.

I think it would be very interesting to see how performance of a 6mm AK74 would compare to 5.45mm.

So, when do you start building one?
