Mark 6 1-6x20mm (34mm) M6C1

The all-new Mark 6 1-6x20mm scope was engineered based on the years of elite riflescope making expertise in order to deliver relevant performance features to competition shooters and tactical operators in mid-range to CQB scenarios. Built around a rugged, ultra-bright daylight visible illumination system, the Mark 6 1-6x20mm offers a true "both eyes open" situational awareness at 1x, while also offering the ability to identify and engage targets out to several hundred meters at high magnification. Several notable mechanical/optical advances include the new low-profile, mil-based ZeroLock™ windage and tactical features that are common throughout Leupold’s Tactical product line. Hands down, the most commonly used phrase we hear from tactical end users is, “smaller, lighter, faster” when describing the perfect optic. Leupold Tactical Optics; we listened. And delivered. elevation dials to prevent unintentional adjustment in the field and caliber-specific front focal plane reticles.

Rated 5 out of 5 by from Mark 6 3-18 is My choice for a PRS optic! After trying one of these scopes out, I got rid of my Vortex Razor HD II 4.5-27 to buy the Mark 6 3-18 with a H59 reticle. It is lightweight, rugged, crystal clear, and offers a great warranty. The turret locks on the scope are genius, and help a ton. I had a chance to directly compare this scope in low AM & PM light conditions to the razor, and that poor Vortex couldn't perform with the Leupold Product. I shot with a 6.5 creedmoor all the way out to 1 mile using this scope, and I connected with my target. The return to zero on this scope is fantastic, and its always spot on when I re-install it on the gun. Great Optic, Great Warranty, what else could you ask for?!?!?!?!

Rated 5 out of 5 by from The Mark 6 is a robust rile optic! I'll never mess around with MOA scopes again! MRAD scopes are soooo easy, divide your distance by one thousand, then voila! 10 clicks will move your point of impact that many inches! (e.g. 300 yards = 10,800 inches, divide by 1,000 = 10.8 inches). Ten clicks will move the POI 10.8 inches at 300 yards! Obviously the scope is super high quality, it's a Leupold!

Rated 5 out of 5 by from Mark 6 1-6 Best 3-Gun Scope period. I have ran quite a few competitor optics for 3Gun, and after using the Mark 6 1-6 I will never shoot 3-Gun with another optic again. The CMR556 reticle on the First Focal plane is absolutely a wonderful tool to have. The red dot illumination on 1x makes it so you can hose targets as fast as you can pull the trigger.

Rated 5 out of 5 by from Amazing Clarity I bought this scope 2 weeks ago and this is hands down the clearest rifle scope in my cabinet. Pesky wood chucks at 300 don't stand a chance.

Rated 5 out of 5 by from Amazing 3 gun optic! I had the privilege of running the Mk6 1-6 at a 3 gun match recently and was incredibly impressed. The glass is crystal clear. The TMR-D reticle is amazing for range shots. The illumination is daylight bright! Overall amazing optic! And rock solid. I think I could have hit it against a tree and it would hold zero!

Rated 5 out of 5 by from Light, sharp and powerful, the Mark 6, 3-18. My first Leupold optic, and all I can say is I can't believe I waited so long to get into a Mark 6. So light, powerful and crisp, its all most people will ever need in a magnified optic.

Rated 5 out of 5 by from This has what I want I liked it so much I bought another one. When I bought it there was a promotion for a Leupold mat. It has been a year and I still have not seen the mat.

Rated 4 out of 5 by from Great Scope But.... I highly recommend this scope. I used it on a M110 and really enjoyed it. However for military use I don't like the zero stop because of the need to be able to dial down when attaching NVD's. Also I would like to see a small knob incorporated on the zoom to make it easier to quickly dial in and out.

Xtended Twilight Lens System

Now your hunt can reach further into the twilight than ever before possible, with our exclusive new Xtended Twilight Lens System™. It goes a step further than even the Index Matched Lens System®, using Leupold’s® index matched glass with wavelength specific lens coatings designed to optimize the transmission of low-light wavelengths. When most scope manufacturers quote percentage of light transmission, they usually mean at 550 nm, the green wavelength where the human eye is most sensitive. The challenge is that in twilight conditions, green light disappears and blue/violet light takes over. Your eye is already handicapped when it comes to seeing the blue/violet spectrum, and if your scope is cutting too much of it out, soon you won’t be seeing anything. The Xtended Twilight Lens System places extra emphasis on matching coatings to glass indices to achieve the best possible transmission of the blue/violet spectrum, without sacrificing the color balanced light transmission across the visual spectrum of the Index Matched Lens System. When we combine that with superior computer-generated optical design, lead-free lenses of unsurpassed clarity and quality, and 100 years of manufacturing excellence, you have a scope that gives you the details of low-light scenes in greater definition and luminance than any other scope in the world.

DiamondCoat 2

Exterior lens surfaces are treated with DiamondCoat 2™, an ion-assist lens coating, for higher light transmission and the greatest level of abrasion resistance we’ve ever offered. DiamondCoat already exceeds military standards for hardness and durability. DiamondCoat 2 offers unsurpassed durability and will prove its worth in the wildest places on earth. DiamondCoat 2 has the additional advantage of assisting in light transmission, for greater brightness, clarity and contrast.

Front Focal Plane (FFP)

The reticle magnifies along with the image, so you can estimate range at all magnification settings. These reticles are ideal in tactical situations, yet also provide greater accuracy of range estimation for hunters and target shooters.
