Built on an incredibly tough one piece 35mm main tube and using a state-of-the-art optical system and erector mechanism, the VORTEX Razor HD 5-20x50 Riflescope, EBR-1 MOA Reticle, 35mm Tube (RZR550) delivers superior accuracy and rugged reliability under the harshest conditions.
This model riflescope uses a first focal plane reticle. This style of reticle maintains its subtensions regardless of magnification change - the reticle appears to grow and shrink as the magnification changes. The main advantage to this style reticle is that the reticle subtensions used for ranging, holdovers and wind drift corrections are always accurate at any magnification.
APO objective lens system corrects color across the entire visual color spectrum - virtually eliminating chromatic aberration across the entire field of view. Optically indexed lenses delivers optimum image sharpness and brightness with true reticle use for full ranging and holdover from edge to edge because of computer-controlled alignment during construction.
XR coatings deliver incredible image detail with extremely high resolution and light transmission. XD (Extra-low Dispersion) glass objective lens elements made of extra-low dispersion glass enhance image resolution and are carefully selected and precision crafted to exacting standards for true-to-life images of startling clarity and color accuracy.
The Razor HD riflescope uses a side focus parallax adjustment which, when properly set, eliminates parallax errors. Parallax is a phenomenon that results when the target image does not quite fall on the same optical plane as the reticle within the scope. When the shooter's eye is not precisely centered in the eyepiece, there can be apparent movement of the target in relation to the reticle, which can cause a small shift in the point of aim. Parallax error is most problematic for precision shooters using high magnification.
Vortex Razor riflescopes have the Radius Bar to visually assist in keeping track of turret rotations. By watching the position of the bar while making elevation adjustments, the shooter is able to quickly track full, half and quarter rotations.
This riflescope incorporates the RZR Zero Stop feature. After the rifle is sighted in, the RZR Zero Stop allows fast, easy return to the original zero point when large multi-revolution elevation corrections have been dialed into the riflescope.
Friction Reduction System provides superior durability, repeatability and accuracy for the life of the product. Prevents galling or deformation of the erector screw contact point because the heat-treated, hardened-steel pad floats on the end of the turret screw and interfaces with a hardened steel ring on the erector tube for steel-on-steel contact.
ArmorTek is an ultra-hard, scratch-resistant lens armor, chemically bonded on the outer glass surfaces. ArmorTek's unique stain-proof topcoat features a slippery surface that actually repels the oil and corrosive salts from fingerprints. Dust, dirt and smudges are easily wiped away without fear of scratching the optical glass beneath.
Designed to maximize long distance shooting and ranging abilities, the EBR-1 MOA reticle can be used to effectively determine ranges, holdovers, and windage corrections. Ultra precision laser etching on the glass reticle ensures that MOA specifications can be kept to the tightest tolerances possible. The fine center crosshair subtensions on the EBR-1 reticle were carefully chosen to provide the optimum balance between precision aiming and low light visibility.
The Razor HD 5-20x50 Riflescope comes with flip cap ocular lens cover, flip cap objective lens cover with killFLASH ARD, 4-inch sunshade, bubble level, 2mm hex wrench, CR2032 battery and the VIP Unconditional Lifetime Warranty.
