Designed and built for precise long-range shots in extreme environments, the Vortex 4.5-27x56 Razor HD Gen II Riflescope combines superior optical and construction elements to produce a rugged scope for hunters and tactical professionals alike.

Engineered with a broad zoom range, an oversized objective, superior glass, and specialized optical coatings every optical component complements the other to provide clear and bright images at all magnifications and lighting conditions, especially when sighting a smaller target at extreme ranges on the highest zoom. The apochromatic lens is made of high-density (HD) extra-low dispersion (ED) glass to maximize light transmission, minimize distortion, and virtually eliminate chromatic aberration. All air-to-glass surfaces have Vortex's index-matched XR Plus anti-reflective coatings which are specifically formulated for the glass to which they are applied to minimize light loss and maximize image brightness, clarity, and color accuracy. This combination of coatings and optics, combined with its broad magnification range and MIL-based ranging reticle and turrets, creates a riflescope uniquely capable of precise long-range shots.

An array of construction details protect the precision optics and enable the scope's use in the most extreme conditions. It is made of lightweight and durable aluminum alloy treated with a low-reflectivity and scratch-resistant matte-black anodized finish. The 34mm diameter one-piece main-tube is oversized for additional strength and maximum light throughput and allows for the wide elevation adjustment range that smaller tubes couldn't provide. It is filled with inert argon gas and O-ring sealed to make the entire scope waterproof and resistant to internal fogging when moving through extreme changes in temperature or environmental conditions. A 4" removable sunshade is included to reduce glare and prevent lens flare when pointing the scope in the direction of the sun.

Optical Performance

  • Ideal for long-range use, the powerful 4.5-27x zoom magnification allows user to see a wide landscape for observation with the ability to zoom in and make positive identification
  • Large, oversized 56mm objective is optimized for use during pre-dawn and dusk hours and ensures views remain bright and clear even when set at maximum zoom
  • Proprietary XR Plus anti-reflection fully multi-coated optics are index-matched to the specific glass they are applied on to maximize light transmission for accurate color fidelity and improved contrast and clarity
  • Apochromatic objective lens system uses complementary lens glass that provides accurate color balance without distortion
  • High-density (HD) extra low-dispersion (ED) glass corrects chromatic and spherical aberrations to eliminate off-axis comas and improve color and contrast
  • Plasma Tech coating application process enhances coating's durability and long life
  • ArmorTek ultra-hard scratch-resistant coatings protect from scratches, debris, dirt, and oil
  • 25.3-foot field of view at 100 yards on 4.5x, 4.4' on 27x

Partially Illuminated Reticle

  • First focal plane placement retains accurate reticle subtensions at all magnification to improve accuracy
  • HORUS TREMOR 3 MIL-based ranging reticle
  • Specifically designed for long-range shooters
  • Open upper half provides a free and uncluttered field of view
  • Hash marks and stadia lines on horizontal axis
  • Lower half offers a variety of markings for bullet drop, wind corrections, spotting, and ranging
  • Illuminated dots on the center point and lower portion aid BDC and other adjustments in low light
  • Etched on glass for permanence without the possibility of shifting over time
  • Eleven selectable brightness levels to ensure clear visibility in all light conditions
  • Illumination powered by one included CR2032 battery

Turret Details

  • Exposed tactical turrets allow for fast adjustments in the field without tools
  • L-Tec Zero-Stop turrets provide fast and easy-to-read elevation and windage adjustments, and prevents resetting past zero point after the shot is taken
  • External rotation indicator on elevation turret provides a visual and tactile reference for the number of rotations that have been made
  • Precise 0.1 MRAD impact point correction
  • Broad 33 MRAD total elevation adjustment range is optimized for long-range use
  • 14 MRAD total windage adjustment range
  • 10 MRAD total travel per dial rotation
  • Wear-resistant low-friction turrets are made for long-life with smooth and accurate rotation
  • Micro Adjust Zero Setting allows nearly infinite position setting while zeroing the scope for optimal accuracy

Use and Handling

  • Fast-focus eyepiece: External Rotation Indicator provides quick visual and tactile reference of elevation settings
  • Lockable illumination knob sets the user's preferred reticle brightness setting
  • Parallax correction from 25-yard to infinity, with adjustment dial easily accessible from most shooting stances/positions
  • Long 3.7" eye relief provides a generous eye box for comfortable use and mounting placement flexibility

Construction Details

  • Large 34mm single-piece main tube improves strength, light throughput, and optical alignment while providing the room required for the wide elevation adjustment range
  • Lightweight and strong aluminum alloy body
  • Low-reflectivity matte black hard anodized finish
  • Argon-filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme changes in temperature or environmental conditions
  • Low-friction erector system provides durability and repeatability even after a lifetime of shots
  • Includes 4" removable sunshade to reduce glare and prevent lens flare when looking toward the direction of the sun

Vortex Razor HD Reviews

Improved H59

Vortex continues to push the bar when it comes to Quality products at every day pricing. Backed by their unquestioned warranty and now available in the Tremor 3. Hard to beat this scope for the money.

Almost feels unfair. It’s that good.

As a relatively new shooter and brand new long range shooter, I knew I would need all the help I could get from a quality optic. Being so happy with my 1-6x Razor, I elected to give this optic a shot on my Daniel Defense Delta 5 Pro. To say it makes it unfair is almost an understatement. I had never previously shot out past 250 yards and I managed to hit steel at 1040 yards within a few shots with no coaching or guidance thanks to this optic and it’s intuitive turrets. Once zero’d it becomes almost impossible to miss thanks to the clarity and the usability of this optic/reticle. I was even able to put my 59 year old mother behind my rifle and she connected with the same target on her first pull of the trigger and she’s never even fired any rifle before. I seriously could not be any happier or any more amazing with the quality of ALL Vortex products. They’ve earned a life long customer out of me.

One of the best scopes for the price

can you change the eye piece?
Asked by: Anonymous
The eyepiece unscrews and is easy to remove, but there are no other eyepieces that can be used with this scope (i.e. there's no wide field eyepiece for digiscoping)

I just wanted to ask about the new once piece focus ring on the new model? I am a little worried about it as the last model had a course and fine focus and I wanted this primarily for target shooting. Is the new swarovski type focus ring just as good as the old fine focus or should I look for another brand of scope? Thanks.
