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.

XD™ Lens Elements Extra-low dispersion (XD) glass increases resolution and color fidelity, resulting in crisp, sharp images.
XR™ Fully Multi-Coated Proprietary coatings increase light transmission with multiple anti-reflective coatings on all air-to-glass surfaces.
Second Focal Plane Reticle Scale of reticle maintains the same ideally-sized appearance. Listed reticle subtensions used for estimating range, holdover and wind drift correction are accurate at the highest magnification.


Tube Size 1 inch diameter tube offers a versatile blend of adjustment, size and weight for a wide variety of shooting applications.
Aircraft-Grade Aluminum Constructed from a solid block of aircraft-grade aluminum for strength and rigidity.
Waterproof O-ring seals prevent moisture, dust and debris from penetrating the binocular for reliable performance in all environments.
Fogproof Nitrogen gas purging prevents internal fogging over a wide range of temperatures.
Shockproof Rugged construction withstands recoil and impact.
Hard Anodized Finish Highly durable hard-coat anodization provides a low-glare matte surface and helps camouflage the shooter's position.
Precision-Glide Erector System This system ensures the components in the zoom lens mechanism glide smoothly and cleanly through all magnification ranges.
Exposed Tactical-Style Turrets Provide fast, accurate and easily read elevation and windage adjustments.


Radius Bar Fiber optic turret rotation indicator provides a highly visible and tactile point of reference for turret rotations.
Magnification Rib The raised rib on the magnification ring facilitates fast magnification changes in the heat of action.

Rated 5 out of 5 by from The easiest scope to sight in. I purchased a vortex diamondback tactical scope on Black Friday 2016. I sighted it in at 50 yards because I was having trouble getting my other scopes on paper. At that range I held three round high and left at 1:00. After I made my adjustments, I fired 3 more rounds and was dead on. I moved my target back to 100 yards I fired my second group. Still right where I wanted it. I made my second adjustment to be two inches high at 100. Needless to say I filled my tags in the first week of rifle season. I am very happy with Vortex scopes. I plan on buying more to replace the scopes I have on my other rifles. Thank you Vortex for a great product.

Rated 5 out of 5 by from Absolutely worth it! Bought a Savage Model 11 T in .233Rem. It came with a Nikon 3-9x40 BDC Scope. Took the Rifle Coyote hunting 2 weeks ago. With Winchester Silvertip 55gr I achieved a group of 1.56IN at 50M. I didn't get a shot that weekend on a yote. But I knew the gun was better. I ordered the Diamondback Tactical w/ VMR-1 Reticle. Today with crud weather conditions and same ammo, Winchester Silvertip 55gr, my 50M zero was tighter than a dime. My group at 100M was 0.78IN. There isn't a safe coyote in the county now. The scope was effortless to zero. And I have no doubt that this gun/round/scope package is the best I have in my safe. I absolutely love it.

Rated 5 out of 5 by from World class optics Bought this having owned a viper pst. This is as clear and bright.perfect for my .223.Vortex are the only glass anyone should consider.corrections made through the turrets are perfect.field of view bright clear with a precise reticle for hold overs in second focal plane.easily zeroed turrets with no need for a tool.vortex are the only optics I will ever purchase.I've recommended to family and friends.this is my second vortex but not my last. I'm in the military and have shot long range with other top end optics but vortex far exceeds them and with a realistic price tag to match. One word to describe vortex , , , precision !!!!!

Rated 5 out of 5 by from Loving it so far... tomorrow is the real test. Just mounted my DB Tactical 3-9x40 (SFP) this morning. Looks great. Can't wait to get it on the range tomorrow. Appears to be a quality scope with nice, tight tolerances. Love the VRM-1 MOA reticle. Also purchased the optional 4" sunshade. The pic is with the sunshade on. Turrets are nice and easily visible for an old man like me. I love everything about this scope so far. Will get it in the ballpark with a laser bore sight tonight, then head to the range tomorrow. Feeling proud to be a new member to The Vortex Nation! Thanks Vortex!!!

Rated 5 out of 5 by from I finally found my perfect scope! Last week I bought an ISSC SPA TAU .22 lr and since it had quite a price tag I decided to buy a decent scope for it. I settled for this scope after reading many reviews and talking with a local dealer about it. Only after I bought this scope I realzied how perfectly it fits to my needs. You see, being a European it's a real pain calculating with MILS and MOA - even worse if you've got a Mildot-reticle and MOA-turrets on one scope. Translating all these measurements to meaninful metric numbers drives me nuts. Now it's all very easy with this scope since it has a MOA-reticle and MOA-turrets. Now I 'm just picking a distance for zeroing the rifle (e.g. 70 meters) and whenever I need to shoot to, say 100 Meters I just use the maximum magnification and measure in MOA the new POI and with the MOA-turrets i simply dial in the correction and note it in my dope book. No need for headache-calculations anymore!

Rated 5 out of 5 by from Worked at 1000 yards! Used this at a long ranged shooting class. The turrets made dialing 1000 yards quick and simple. Target was an 18 inch silhouette target. Once I dialed in, got 3 out of 5 shots. Rifle was just a basic Ruger American. When asked to switch to the 660 yard challenge target (8 inch) made the turret adjustment and hit on the first shot. Awesome!
