The KonusPro 3x-9x50 offers a larger objective lens for those looking for increased light transmission. In fact, the 50mm lens will gather 156% of the light being transmitted through a 40 mm lens. This scope also features an unbreakable glass engraved, 30-30 reticle. The multi-coated optics provide enhanced light transmission, and finger adjustable turrets are easily dialed in, even with gloved hands. As with all Konus scopes, they are nitrogen purged for true waterproof & fogproof integrity, as well as being shockproof.
