Vortex Razor HD Gen III Review: Precision Optics Unleashed

Released in January 2024, the Vortex Razor HD Gen III 6-36×56 FFP was engineered for precision—from the field to the firing line. Whether you’re engaging targets in a tactical environment or competing at extended ranges, this optic delivers elite-level clarity, robust construction, and outstanding low-light performance to give shooters a decisive edge when it counts most.

Measuring 15.3” in length, the Razor HD Gen III 6-36×56 First Focal Plane (FFP) is a purpose-built optic that pairs seamlessly with full-length bolt guns and semi-automatic platforms alike. Its wide magnification range and precise parallax adjustment make it equally suited for long-range competition or hunting during low-light fall conditions. Built to endure harsh use, the optic housing is protected by Vortex’s ArmorTec® coating in a Stealth Shadow finish—resisting scratches, oil, and debris to maintain a clear sight picture when it matters most.

Built from a single piece of anodized, aircraft-grade aluminum, the Razor HD Gen III features a robust 34mm main tube paired with a large 56mm objective lens—giving the optic its commanding presence and enhanced light-gathering capability. The adjustable eyebell assembly supports a versatile 6-36x magnification range with a consistent 3.5” of eye relief. To ensure reliability in any environment, the internal components are IPX7 O-ring sealed and argon gas purged—offering full protection against moisture intrusion and internal fogging.

The Razor HD Gen III features Vortex’s HD Optical System, which uses high-quality glass to enhance resolution and reduce chromatic aberration—resulting in sharper images, better color accuracy, and improved light transmission. Additionally, the lenses are index-matched to maintain true-to-life color across the entire field of view.

The Razor HD Gen III 6-36×56 is available with Vortex’s glass-etched EBR-7D reticle in either MOA or MRAD (featured in this review) configurations. All air-to-glass surfaces are treated with XR™ Plus anti-reflective coatings to enhance light transmission and image clarity. The reticle also features illumination, powered by a CR2032 battery, with a continuous runtime of approximately 36 hours.

The locking illumination dial features a push/pull design with 10 intensity levels, allowing precise control over the reticle’s center illumination—including multiple settings optimized for low-light conditions.

The 6-36×56 optic features exposed locking turrets for both elevation and windage, using Vortex’s L-Tec+ Zero System. After removing the set screw, adjustments can be made easily, with built-in grooves to help maintain consistent alignment. Both turrets adjust in 0.1 MRAD increments. The parallax is adjustable from 10 yards to infinity, allowing precise focus across a wide range of distances.

Editor’s Note: For the purposes of this review, the Razor HD Gen III 6-36×56 FFP was paired with a 34mm scope mount from American Defense Manufacturing, but it did not play a factor into the review of the performance of the optic itself.

Product Evaluation Scores:

  • Cost – Average (3/5): The Razor HD Gen III 6-36×56 has a list price of $4,799.99 and combines premium glass, a rugged housing, excellent low-light performance, and an illuminated reticle—backed by Vortex’s lifetime “No Questions Asked” warranty, which sets it apart from many competitors. While some third-party retailers offer it for as low as $2,999, buyers should be cautious and purchase only from trusted vendors, as counterfeit or gray-market optics are occasionally sold by unverified sources. For comparison, similar high-end optics include the NightForce ATACR 5-25×56 F1 ($3,550), the Schmidt & Bender PM II 5-25×56 ($4,599), and the Leupold Mark 5HD 5-25×56 ($2,599). At full retail, the Razor sits at the top end of the price spectrum, but given the build quality and glass performance, it’s competitively and appropriately (or average) priced. At third-party prices, it becomes a strong value in the premium optics market.
  • Comfort – Good (4/5): From a comfort aspect the Razor held a good eye relief with full view down the optic. This eye relief however, became notably (but not uncomfortably) shorter at maximum zoom. The glass itself was amazingly clear, with no hint of colored tint around the edges of the field of view due to the gas purging, and high color definition for targets down range. The turrets did provide a clear audible and tangible click with each increment changed, and remained firmly locked into place throughout evaluations—assuming the locking set screw for the L-Tec+ system was removed. Moreover the line markings on the elevation and windage correctly aligned with each marking. The parallax adjustment did help to maintain a comfortable  image sharpness within the context of the 6-36 magnification. The extended (or pop-out) turret for the illumination reticle also had a tangible feel to it, and each click made it easy to judge each setting difference between brightness values. However, while the reticle illumination was visible in full daylight, it was obviously clearer against a dark background, target, or in low-light settings.
  • Durability – Excellent (5/5): In terms of durability, the Razor HD Gen III is finished in a low-glare matte black (some may see it as a grey) and treated with Vortex’s ArmorTek® coating, which provides resistance to scratches, oil, and abrasions during regular use. The optic housing is built from a single piece of aircraft-grade aluminum, contributing to its overall rigidity and resistance to impact. The demo unit used for evaluation had some minor cosmetic wear—some pre-existing and some acquired during transport or routine handling—but these did not affect the optic’s performance. The internal glass elements remained firmly in place, and the lenses showed no signs of scratching, fogging, or distortion throughout use and in the Missouri summer heat and humidity. The Razor is also shock-resistant, waterproof, and internally nitrogen-purged, which helps prevent internal fogging and protects against rapid environmental changes. These design features held up during varied conditions, including rapid temperature shifts and rough handling, with no loss in function or clarity. Vortex includes several accessories—such as a lens cloth, sunshade, and throw lever—to help maintain the optic and protect it during storage or transport. Additionally, the Razor is backed by Vortex’s lifetime, no-questions-asked VIP Warranty, which covers damage or defects for the life of the product.
  • Functionality – Good (4/5): Functionally, the Razor HD Gen III 6-36×56 delivered a broad and usable magnification range, with image clarity well-preserved throughout. The HD Optical System offered excellent resolution and color fidelity, maintaining high contrast and minimal color degradation even at maximum zoom. This was largely due to the use of apochromatic lenses, which are designed to maximize light transmission and reduce chromatic aberration, particularly at longer distances. The adjustable fast-focus eyepiece allowed for precise diopter tuning, keeping targets sharp across various distances. During evaluation, hitting steel targets at 300 yards was consistent and straightforward. The EBR-7D MRAD reticle used in this model provided clear, precise holdover and ranging marks. The optic’s first focal plane (FFP) design ensured that reticle subtensions remained accurate across the full magnification range. As magnification/adjustment increased, the reticle remained sharp and readable, without loss of definition. The illuminated reticle performed well in low-light or shadowed environments, though it was less visible in full daylight—even at higher brightness settings. Windage and elevation turrets featured Vortex’s L-Tec+ Zero System, which allows the user to unlock the turret and adjust the numerical dial after sighting in, but only after the set screw was removed. Once the set screw was placed back in the turret retained a solid lock. However, unlike Vortex’s RevStop Zero System found in the Venom series, the L-Tec+ Zero System does not allow for full turret removal to re-index the zero stop position. As a result, returning to a true mechanical zero between distance changes requires the user to either track adjusted values or rely solely on the reticle for compensation. This may present a limitation in competitive settings where distances vary significantly between engagements—something Vortex may want to address in future iterations.
  • Weight – Average (3/5): The Razor HD Gen III 6-36×56 weighed in at 45.1 ounces, with much of that weight coming from its anodized, aircraft-grade aluminum body, designed to handle repeated recoil cycles without shifting zero. While heavier than some optics, the added mass contributes to overall durability, ensuring the scope remains stable during transport and resistant to incidental impacts in field or range environments. Several design choices contribute to the Razor’s weight. Its 6-36x magnification range requires a more complex internal lens system than optics limited to 25x, and the 56mm objective lens—combined with high-density APO glass—adds both size and optical capability. The 34mm main tube allows for greater elevation adjustment and light transmission but also increases material volume. Additionally, the oversized, lockable turrets using the L-Tec+ Zero System are built for precision and tactile control, but their robust construction adds to the scope’s overall heft. By comparison, the NightForce ATACR 5-25×56 F1 (37.6 ounces), the Schmidt & Bender PM II 5-25×56 (38.4 ounces), and the Leupold Mark 5HD 5-25×56 (30 ounces) are all notably lighter. While the Razor is on the slightly heavier end of this group, its weight reflects a deliberate design focused on long-range stability, image clarity, and mechanical precision—making it appropriately (or averagely) suited for users who prioritize performance and ruggedness over portability.

Overall Rating – Above Average (19/25)
