Capped turrets

Capped turrets are the most usual turret type on hunting scopes, where the turret covers are removed only on rare occasions, when the scope is zeroed. Due to the caps, the turrets are well-protected against water, dust, and unintentional damage. On most of the hunting scopes and on some wide-angle tactical scopes, the turrets under the caps have low height. On target scopes, this is different, since most turrets are high and easy to dial. In modern rifle scopes, turrets caps also hold the spare battery for the illumination.
