There are other big bore ar15 uppers also such as the 458 SOCOM.
It is my understanding that the 450 as well as the other big bore uppers can be extremely accurate if used within the range that they are designed to work.
The 7.62x39 in itself does not have accuracy issues. The problem comes in when you shoot cheap surplus in AK rifles that are designed to shoot within a circle that is eight inches at 100 yards. Remember that the 7.62x39 is that case that the 220 Russian is based upon which developed into the 6mm PPC & the Grendel.
