Designed for long-range shooting applications in low and challenging light, the Vanguard 4-16x50 Endeavor RS IV Riflescope puts a flexible and reliable optic in your hand that is further enhanced with the addition of a simple and intuitive duplex crosshair reticle with a clearly defined center aiming dot that is easy to see in both fading light and full daylight.

The Endeavor RS IV is outfitted with a zoom range that starts at a low 4x power for mid-range plinking and varmint hunting and goes up to a high of 16x that allows for more distant shooting. Its partially illuminated reticle is optimized for the scope's versatile uses and offers selectable intensity levels from dim settings that won't affect vision that has been adjusted to low light all the way up to a bright setting that makes your aiming points clearly and distinctly visible in full daylight. Complementing the magnification range and reticle design are low-profile capped zero-reset windage and elevation turrets that adjust as much as 50 MOA at 1/4 MOA per click increments to improve your first-shot accuracy.

Optically, Vanguard employs a large 50mm objective lens that gathers the copious amounts of light to ensure views remain bright and clear in low light or if you are observing targets at long range on high power. The scope utilizes Hoya extra-low dispersion glass that corrects aberrations, so views are clear and undistorted with accurate color and improved contrast and clarity, while anti-reflection MultiGuard lens coatings further improve light transmission. The large 30mm maintube maximizes light throughput and is made of a light and durable aluminum alloy treated with an anodized finish for abrasion resistance and longevity. To withstand the harsh elements of the trail, the housing is nitrogen filled and O-ring sealed to make it waterproof, submersible, and resistant to internal fogging. Vanguard includes protective front and rear flip-up lens caps, so you can react quickly when opportunities present themselves.
