Guns are OP because:

a) Stats are too good

b) It does too well at what it's supposed to be used for

c) It can be used for other things

d) Too easy to use

Guns are considered UP because:

a) Stats are too low

b) It doesn't do as well as it should be doing at what it does

c) It struggles in versatility

d) Difficult to use

Prime examples include, as you said, M416 CQB and the M16A3 series. The M416 family does too well at what it should be done and it does well at other ranges. The M16A3 series doesn't do as well, because of its ridiculously low damage rating, high recoil, high spread and average accuracy.

Just my opinions.
