Variable scopes may well be

Variable scopes may well be popular and sell well but I am a fan of fixed power for specialized purposes. Too bad you cut back on fixed power production so I am forced to crank in a setting and keep it there. Anyhow, you continue to make fine products and I like my Leupold scope.

Greta for a BB gun scope

The red dot at the three highest setting is when it's possible to see even in a dark room at night, the hold overs are very hard to see also even when looking at the target, i own three other luepolds and they are all of high quality don't know where the quality went on this one if they won't let me return it I will put it on my grandson's Daisy Red Ryder very disappointed to say the least

Ticked all my boxes

My Mark 3HD 4-12x40 Firedot TMR ticked all my boxes for a shorter barrel . 308 bolt gun. MPVO. Very usefully illuminated. Very light weight. Mil-Dot second focal plain. MRAD turrets. Elevation good to 600m, with stop. Good glass. Good warranty and real support. Lacking a fifth star because they included the wrong size Allen for the elevation turret. Should be 1/16", not 0. 05". Also there is play in the windage before first click. And I could only get it at MSRP, which was expensive after adding their nice caps and good rings.

This scope is mounted on

This scope is mounted on an older refurbished Anschutz . 22 LR. The gun is utilized as a plinker/trainer at 25 and 50 yards. For me, the power range and reticle are perfect for the guns intended use. The features and quality of the scope for the price are outstanding. I am very happy with my purchase.

Beautiful Tactical Simplicity

This lightweight little scope is fantastic for the price. Optical clarity is good. Has the tried-and-true Mil-Dot reticle. The reticle is in the second focal plane. So simply leave your scope on 9 power magnification, and your mils are correct. This is not a scope for extreme long range. With this scope you get 5.6 Mils of elevation adjustment. That gets my rifle out to 700 yards. 5.6 mils is in slightly less than one revolution of the elevation dial. The elevation dial also has a zero stop. Those two features mean it is impossible to become lost in what revolution you are on. Windage dial is just for zeroing the scope. You will have to use the reticle to correct for wind with this scope.

Solid for what it is.

Solid for what it is. Lightweight, clear glass. Easy hits with a 50 meter zero, 2.7ish mil hold at 500 yards (I know, the distance measurements are mismatched) with 5.56 55 grain from a 16" barrel. Firedot is daylight bright. The windage knob is where they saved money and weight. It is awfully mushy. It is a guessing game when trying to make small zero adjustments to the windage. After zeroing it? hopefully you don't swap optics often otherwise zeroing is going to get old. This optic should be almost permanent on your firearm. If so, after zeroing, you don't ever touch the windage knob anyway. Within any purposes I might have for this, it is a five star optic, given they had to cut something, they did it where it makes sense. I pair this with an aero precision ultralight mount and an offset holosun comp red dot to do 1x better for me than a tube could (making 1.5x perfect), and it is super fun to work with. Magnification isn't just about distance- it can be very useful for precision at closer targets too. Good to go for a variety of purposes. Offset red dot lets you hose close transition targets a little faster.

It's a Leupold optic. There's not much more to say. Glass is super clear, edge to edge. The TMR reticle is easy to utilize, and once you know your round's trajectory, it's pretty much point and press the trigger. The dot intensity is easily fine-tuned for different lighting conditions, but also simple enough to find the happy medium brightness setting. The 1.5 magnification does not hinder the ability to use this scope for a reflex sight at all.

I'm very happy with the scope. I purchased the rings and mounts for a Mauser action at the same time. Ideally I might have been advised that the scope is too short to be mounted directly to the receiver, and requires a rail system. Lack of research on my part, but potentially a way to improve the scope selection process.

By James D.

Clear glass, rugged design, and a good choice for my 308 AR rifle.

Great short/mid range scope

By Jeffrey D.

Scope has good lense clarity and light transmission. Hash marks are right on. Overall size is great for braced pistols. Regarding Really?! review. It should read ?really dumb***?; 1 star on a premium made & backed scope, because you can?t read the specs before purchasing. People like you screw up overall ratings for others that are shopping based on 4 or 5 stars only products. For up close & fast, a good 1.5 is still fine for both eyes open.

While steeped in a rich heritage of crafting rugged and reliable riflescopes, Adorama presents the Mark 3HD 4-12x40mm Riflescope, a versatile tactical scope designed for the discerning shooter. This matte black riflescope is ideal for mid to long-range shots, enhancing the performance of any rifle in your collection.

Engineered with MIL-based adjustments and reticles, the Mark 3HD series offers high-definition performance, an exposed elevation adjustment dial, and a low-profile power selector with an integrated throw lever. This makes it an excellent choice for those seeking a durable, precise, and repeatable scope.

At the heart of this riflescope is Leupold's Elite Optical System, delivering superior light transmission, glare reduction, and resolution. These features are essential for hunters and shooters who demand consistent performance throughout the day.

The scope's illuminated FireDot reticle, complete with seven brightness settings and an easy-to-use illumination dial, ensures quick target acquisition, even in harsh daylight conditions.

The Mark 3HD 4-12x40mm Riflescope is designed, machined, and assembled in our Oregon factory. It undergoes rigorous testing to ensure it's rugged, 100% waterproof, fogproof, and guaranteed for a lifetime of performance.

Key features of this riflescope include a 3:1 zoom ratio, common in many scope models, providing three times more magnification at high power than at low power. This allows you to adjust your power for close encounters or long-range shots.

The scope's high-definition, calcium-fluoride lenses ensure incredible clarity at all magnification levels. The illuminated reticle aids in faster target acquisition in low-light situations.

The ZeroStop system creates a backstop when returning the dial back to zero, preventing accidental full revolution turns in the wrong direction.

Leupold's Custom Dial System (CDS) allows you to customize your turret (adjustment dial) to your exact ballistics and environmental conditions. Once your new custom dial is installed, simply range the target, turn the dial to that number, and aim dead on.

The riflescope is waterproof, fogproof, and shockproof, thanks to Leupold's pioneering modern technology using advanced internal gasses and sealing methods. These withstand extreme temperatures, elevation changes, and shocks, ensuring the optics stay moisture-free and crystal clear for life.

The FireDot TMR Illuminated Subtension and Magnification feature ensures the riflescope will measure (subtend) correctly when set to the highest available magnification. The reticle's apparent size in the field of view may vary between models of riflescope.

In conclusion, the 4-12x40 Mark 3HD Riflescope, Matte Black with Illuminated Second Focal Plane FireDot TMR Reticle, P5 Dial, 30mm Tube is a versatile, high-performance addition to any shooter's collection.
