The new SlugHunter features several technology upgrades that will satisfy even the most demanding shotgun hunters. A bright new optical system, remarkable hand-turn reticle adjustments with Spring-Loaded Instant Zero-Reset Turrets, and a convenient quick-focus eyepiece make adjustments while in a shooting position a breeze. The SlugHunter 3-9x40 with BDC 200 reticle is an ideal fit for virtually any slug gun and can be used with Nikon Spot On Ballistic Match Technology to take the guesswork out of compensating for sabot/slug drop. With enough power for the longest-range shots and a wide field of view to keep you on close-in or moving game, you can count on the SlugHunter 3-9x40 in any situation. In addition SlugHunter scopes are built with fully multicoated optics for maximum light transmission, even in extreme low light environments.
