This Vortex Optics Diamondback Tactical Rifle Scope has exposed tactical turrets built for dialing elevation and windage allowing quick and precise bullet drop and wind drift compensation at extended ranges. 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.
