Great scope clarity is what you would expect from leupold clear and crisp. Magnification is great and tracking is awesome love how it locks so there is no accidental bump movement when packing it around. Will definitely be getting more to fit all my guns with them

I was on the fence

I was on the fence with the tmr reticle in this scope, but after spending some time with it, it is plenty fine enough for the work i do. I think the pr1 or other more finely reticled would be too thin and unusable in any range other than 12x up. The reticle is clear and usable at 5x all the way up to 18x. Eye box is pretty generous through the magnification range as well. I also love the locking turrets which was the feature that put me here over other options. Im about to replace my other non mk5 scopes that arent already nightforce or razor hd. . . i prefer this to those bc of the locking turrets (my rifle deploys from a pack a lot. . . )

Very good eye relief, crystal

Very good eye relief, crystal clear glass, easy to zero --- but the couple issues I had was it arrived with a stained sun shade (it's an fde colored scope) after contacting leupold I was told they'd take care of but sent me a black replacement. . when contacting them about this I was told they only have black sun shades??? Obviously not because I ordered an fde scope so they are obviously making them for production scopes. At the range sighting in the scope I had an issue that involved not being able to get the scope/reticle low enough. You can take the turret off and bring it lower but I had to go 2 full turns with I thought was quite a bit . . after that was done no issues. It's my first leupold scope but won't be my last.

Great scope, almost perfect

Great scope with very clear glass. 4/5 stars mainly because of 2 specific things: 1. The lines on the elevation turret are very difficult to tell if they are lined up with the reference line. The reference line is only half as wide as the lines on the knob so difficult to tell which 0. 1 mil I'm on. And then the reference line for the windage know is VERY far away from the actual turret. The line should've either been carried through the threads or been placed inside of the threads closer to the knob. 2. The reticle and subtensions could be just a hair thicker. Easy to see at 35x but most people use it closer to 20-25x.

The versatility and user friendliness

The versatility and user friendliness of these scopes are unmatched in my opinion. I have 2 now and plans of getting a 3rd one for my wife's new build. My biggest takeaway has been these scopes ability to grab light. Makes a huge difference on those first light, time to shoot moments.

This is an incredible optic,

This is an incredible optic, I don't want the rest of my review to take away from the performance of the optic or the capability of the reticle, in daylight. I have deducted two stars from what would otherwise be a 5 star optic because of the lack of illumination at this price point. This would be my go to scope if Leupold had included illumination or at least a more bold vertical stadia on the PR-2 reticle which allowed for some level of precision during dawn and dusk at the lower magnification ranges. In lieu of that, even an illuminated center dot would be great. For some reason, Leupold continues to make what would otherwise be phenomenal optics with limited reticle choices, especially if you are looking for an illuminated reticle.

FEATURED REVIEWS

I've had them all

By Hunter

I've owned and shot 95% of your premium brands, Kahles, Nightforce, S&B, Razors, etc and none are as good as this scope. The turrets are incredible, the glass is brighter than all of the other scopes and on par with the Kahles. The glass shows more color to my eye at extreme distance 1500 yds and beyond than my Kahles which is why it replaced it on my 338 Lapua. I've never lost a zero, even on a big caliber and had first round impact repeatability with no issue. Very well thought out and very...

Amazing clarity!!!

By Sonny

I recently shot at an ELR Competition in Wyoming. We engaged targets out to 2100 yards. On that 2100 yard target I could see all of the impact marks from shooters that had previously hit the target.

From the moment you hold the 3.6-18x44 Mark 5HD Riflescope, you'll instantly notice its superior lightweight design, weighing up to 20 ounces less than comparable models. This high-quality, durable riflescope is expertly crafted from 6061-T6 aircraft quality aluminum, ensuring its longevity and reliability in all conditions.

Experience the difference with its exceptional edge-to-edge clarity and extreme low-light performance, enhanced by the Twilight Max HD Light Management System. This advanced system combines exceptional light transmission and glare management to provide vivid, bright, high contrast images from dawn until dusk, making it perfect for long-range target shooting and hunting.

The Mark 5HD Riflescope features a versatile 5:1 zoom ratio, offering a wide field of view at low power and precise target identification at high power. The 35mm Maintube allows for unparalleled windage and elevation adjustment travel, ensuring accurate aiming at all times.

The riflescope is equipped with an illuminated First Focal Plane TMR Reticle, which magnifies along with the image, allowing for accurate range estimation at all magnification settings. This feature, combined with the side focus parallax adjustment, ensures fast and easy parallax focusing from any shooting position, enhancing your shooting accuracy.

The M5C3 ZeroLock Adjustments with 1/10th MIL click windage and elevation adjustments offer more tactile, audible click adjustments, making it easier to put accurate fire downrange faster. The dial illumination control features positive clicks and clear numerical intensity level indicators, including off positions between each illumination intensity setting for quick return to a preferred brightness.

The Mark 5HD Riflescope is 100% waterproof and fogproof, ensuring absolute integrity in all field conditions. It features our exclusive, proprietary Argon/Krypton gas blend, which nearly eliminates the effects of thermal shock and reduces the diffusion of gases sealed inside your scope.

Finally, the riflescope comes with durable, flip-open lens covers and a high-speed throw lever for near-instant magnification changes. Whether you're a hunter or a tactical shooter, the 3.6-18x44 Mark 5HD Riflescope offers the perfect blend of performance, ruggedness, and absolute waterproof integrity.
