I feel a second (sighted-in) scope or red-dot in your pack, is better than iron sights on the rifle because any type of sight can be damaged by a fall.
If you have a picatinny or Weaver detachable mounts, you can swap scopes without losing zero, provided the spare is also sighted-in (and not just bore-sighted).
People are like rifles. Some are tried and true, having great eyes, personality, and fun to be with. Others never seem to hit the mark with you. Still others go off half-cocked. Still, it's nice to know most of them.
