You' ll first probably catch a lot of flack about the 6mm being a little too small for deer. That' s hogwash. It' s a fine caliber if you choose fairly heavy bullets and learn to shoot the gun.

On a gun like that, where long-distance shooting may be in the cards at some point, I would put a variable power scope on it. Maybe one that stretches up to 12 power. Maybe a Leupold or Bushnell Elite.

The 6mm is a flat shooting caliber.....If you put a 4X scope on it, you are limiting the functionality of the rifle.
