The Elite 8-32x40 Riflescope from Bushnell with a matte finish, features fully multi-coated optics for optimized levels of light transmission and crisp image quality. These optics claim a light transmission of 95%. Rainguard HD lens coatings enhance optical clarity by reducing rain, snow, sleet and even your own breath, into much smaller droplets. The tiny droplets scatter less light, ensuring a clearer, brighter view. Bushnell's Ultra Wide Band Coating is an anti-reflection coating which allows the maximum amount of light from the front glass all the way back to the eyepiece. The scope is Argon purged making it waterproof and fogproof.
