First Impressions of Leupold Mark 4HD 1-4.5×24 Rifle Scope, 30mm Tube, Second Focal Plane
As an outdoor and tactical gear specialist, I’ve seen my fair share of rifle scopes. The Leupold Mark 4HD 1-4.5×24 Rifle Scope, 30mm Tube, Second Focal Plane immediately piqued my interest because it promises the legendary performance of the Mark 5HD series in a more compact and lightweight package. This scope is designed for versatility, spanning close-quarters engagements to mid-range shots, and its professional-grade features suggest serious performance.
My need for a scope in this magnification range stemmed from my desire to outfit my AR-15 for both home defense and practical carbine competitions. I was looking for something that provided a true 1x for quick target acquisition up close, while still offering enough magnification to make precise shots out to 300-400 yards. The promise of Leupold quality and a robust feature set made this optic a compelling option.
Upon unboxing, the Leupold Mark 4HD felt solid and well-constructed. The machining was clean, the anodizing even, and the adjustments felt smooth and precise. Its compact size and lighter weight compared to some of my other LPVOs (Low Power Variable Optics) was immediately noticeable and appreciated.
I considered the Trijicon AccuPoint 1-4×24 and the Vortex Razor HD Gen II-E 1-6x before settling on the Leupold. The AccuPoint’s reliance on tritium/fiber optics concerned me in low-light scenarios without a supplemental light, and the Vortex, while excellent, felt slightly heavier than I preferred for this particular build. The Leupold’s combination of lightweight design, proven Leupold glass, and intuitive controls ultimately won me over.
My initial impression was excitement tempered with cautious optimism. Leupold has a reputation to uphold, and I was eager to see if the Mark 4HD lived up to the hype and the price tag of $999.99.
Real-World Testing: Putting Leupold Mark 4HD 1-4.5×24 Rifle Scope, 30mm Tube, Second Focal Plane to the Test
First Use Experience
I first tested the Leupold Mark 4HD at my local shooting range. I mounted it on my AR-15 using a Leupold Mark AR mount, ensuring proper eye relief and a secure fit. I ran a variety of drills from 5 yards to 200 yards, focusing on speed, accuracy, and the scope’s ability to transition between targets at different distances.
The weather was clear and sunny, but the range was dusty from recent construction. The Leupold’s glass provided a bright, clear image, even with the dust in the air. The 1x setting was indeed a true 1x, allowing for rapid target acquisition with both eyes open, almost like using a red dot sight. I was able to quickly engage targets up close and then smoothly transition to 4.5x for more precise shots at longer distances.
The only initial issue I encountered was the stiffness of the magnification ring. It required a bit more effort than I expected to change magnification settings, especially when wearing gloves. However, the removable throw lever helped considerably.
Extended Use & Reliability
After several months of consistent use, the Leupold Mark 4HD has proven to be a reliable and capable optic. I’ve taken it through several practical carbine competitions, a weekend backcountry camping trip (where it endured some bumps and scrapes), and countless range sessions.
The Mark 4HD has held zero perfectly throughout all of these activities. I haven’t had to make any adjustments to the turrets since initially sighting it in. The anodized finish has held up well, showing only minor signs of wear around the edges.
Cleaning the lenses is straightforward. A quick wipe with a microfiber cloth removes dust and fingerprints without leaving streaks. Compared to my previous experiences with budget optics, the Leupold’s optical clarity and ruggedness are noticeably superior. It outperforms other scopes in its class in terms of light transmission, edge-to-edge clarity, and overall durability.
