Mantis Scope Sunshade EXCEPTIONALLY PRECISE: The Mantis is ultra precise right out of the box. Will maintain zero even after several hundred rounds of pellets. EXCELLENT CLARITY: Provides a bright, clear picture of the target thanks to the hiqh-quality optics and parallax (adjustable objective) adjustment. EASY TO USE: Mounts easily, with no tools needed to make elevation and windage adjustments. Simply remove the covers on the windage and elevation turrets and turn the turrets. STURDILY BUILT: Built to last the life of your rifle and beyond. Rugged enough to stand up to the shock of magnum spring-powered break barrel air rifles. GREAT FOR LONGER RANGES: 4-12 variable power capability makes it ideal for medium-/longer-range shooting/hunting, and 12x magnification provides greater precision at distance. The mil dot reticle makes compensating for shots outside of zero range a cinch.
