Vortex Diamondback Tactical 4-12x40 Scope

From Optics Force

Exposed tactical turrets built for dialing elevation and windage allow quick and precise bullet drop and wind drift compensation at extended ranges. When we say precise - we mean it. These turrets track better than any Bloodhound and reliably return to zero every time. A zero-reset feature lets you re-index the zero reference marks on both turrets after sight in while fiber optic rotation indicators integrated into the turrets provide a visual cue of your turret&&';;s position.
