Winchester Supreme quality and performance at the range and in the field ensures you have a dependable optic to trust on your favorite rifle, for your next great adventure on paper or game. Premium lenses transmit the maximum amount of light to your eye through our Winchester WINcoat(TM) multicoating. This coating not only reduces harsh glare but carrier accurate color while providing a durable scratch resistant coating to exterior lens surfaces. Winchester Supreme riflescopes utilize Second Focal Place (SFP) reticles. This means that the reticle stays the same size throughout the scope's magnification range, while only the image changes size. This allows for the most precise shot placement at any distance, and the reticle will always have the same appearance. Key Features: Fully multi-coated lenses throughout the optical system. Excellent low light performance. Beryllium bronze springs. One-piece housing machined from tough A6063-T6 aluminum. Black anodized aluminum exterior. Designed to stand up to 800 Gs of recoil for standard & magnum rifles, and muzzleloaders. Nitrogen filled and sealed optical system for fog and water. Smooth fast focus eyepiece adjustment. Knurled power adjustment ring and turret knobs for a secure grip. Fingertip turret adjustment for windage and elevation.
