M1, Sniping is a completely separate type of long distance shooting. Frankly, it's just long-distance hunting. (with the other roles of a sniper lumped into it).
The tools the military uses for long distance hunting have many funtional and practical limits on accuracy.
There are many AR's that shoot half minute with minimal modifications. There are dramatic improvements that can be made to the Norinco to can make it sub MOA without changing the barrel, but it does depend on the quality of the base rifle.
If you would like to dramatically improve your group size with a norinco, you only need a screw driver: shut the gas port.
