Since it's going to be asked, NTCH is no longer acceptable because:
- the varying depth of changing body armor makes it hard to achieve.
- the variety of optics makes it less favorable to learning to shoot with a variety of CWs.
- the modern battlefield is largely urban where CW changes frequently .
- less situational awareness.
- collapsable stocks vs fixed stocks
- NV
This is why I never used it and one of the reasons I think anything over 1.5 power on a battle rifle is not needed.
