Rated 4 out of 5

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.

Very clear glass, took my MK12 out to 700 yards with ease. My only complaint is the windage marker being slanted, makes it unnecesarily difficult to get an accurate windage dial. So far so good.

Arrived broken. Would not zero

Arrived broken. Would not zero with all shots falling about an inch to the right. Sent back to Leupold (having to pay shipping for an RMA was a nice touch) for repair. Scope was mounted in a different set of rings on a different rifle when returned but had the same result. Just going to cut my losses at this point and go in a different direction.

The perfect scope to keep

The perfect scope to keep my AR10 with a Proof carbon barrel light. Forgiving eye box, wide magnification range, and light. Very quick sight in measuring my miss with the MOA reticle and making adjustment. Verify group/zero, slip your zero stop, good to go. Knobs are easy to read with my older eyes and have great feel and ergonomics. I'm very satisfied with my latest Mark V.

Absolutely love this scope. This is my first 56mm scope, and what a huge difference. I wanted to see how long i could still see deer after sunset. I was able to still see a deer almost 1 hour later. The amount of light this scope let's in, is amazing. I will be purchasing another one. Keep up the great work Leupold!

Awesome scope, clear, lightweight and reliable

Excellent scope. Clear glass and packed with features in a form factor that is lighter than NF and top tier Vortex scopes of the same class. I bought this scope to put on a new rifle I was getting to take on a trip to South Africa. I wanted the illuminated reticle for low light shooting and the tremor 3 reticle for after the hunt on long range shooting adventures. This scope has been a great addition to one of my magnum rifles and an addition to all the other Leupold scopes I have on my other rifles currently.

Great glass, yes it is harder to see the reticle when positioned at 3. 6 but I dont think one thing takes away from the entire scope. I just turned the power up a little bit and I'll leave it at that level. Overall wonderful product and I would recommend this.

The Leupold Mark 5HD 5-25x is hands down one of the best scopes I've used. Glass is razor-sharp, turrets are crisp and repeatable, and the build quality is second to none. Lightweight for its class and holds zero flawlessly. A serious scope for serious shooters.

Second one i got because I was tired of switching it between rifles. That should say it all. I've gotten to used many different brands at matches or helping folks mount and zero scopes. Always choose Leupold. They are also an all American company run by good like minded people. Please keep doing things the way you have been!

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.
