Designed for mid to long-range varmint and predator shooting in low and challenging light, the Vanguard 5-20x50 Endeavor RS IV Riflescope puts a flexible and powerful optic in your hand that is further enhanced with the addition of a simple but highly functional reticle that has a clearly defined illuminated center aiming point that is easy to see in both fading light and full daylight.

The Endeavor RS IV is outfitted with a 4:1 zoom range that starts at a low 5x power for mid-range use and goes up to a high of 20x that allows for accurate shooting at long distances. 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 51 MOA at 1/4 MOA per click increments to improve your first-shot accuracy.

Optically, Vanguard employs a large 50mm objective lens that gathers tremendous amounts of light and ensures views remain bright and clear in low light or if you are observing targets at long range on high power. The scope further 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.
