Bushnell lets you get tight groups with your Rimfire and 40 grain ammo. This scope has hold positions out to 125 yards and has capped turrets that protect your settings in the field. Shots at first and last light are in the bag too, thanks to enhanced optical glass that boosts contrast and resolution. And tough? You bet, thanks to a one-piece, aircraft-grade aluminum body that has no problem standing up to the elements and rough use. You'll also have the confidence to know it won't fog up on you since it's fully IPX7 waterproof.Specifications and Features: Manufacturers Number RR3940BS13 3-9x Magnification 40mm Objective Second Focal Plane DZ22 (BDC) Reticle Non-Illuminated 1 inch Tube Illuminated DZ22 Reticle is designed specifically for a 40 grain 22 LR, with drop points out to 125 yards Fixed Parallax at 100 yards Field of View at 100 yards Low 39' and High 13' 0.25 MOA Per Click 60 MOA Elevation 60 MOA Windage Capped turrets IPX7 Waterproof construction Nitrogen Purged EXO Barrier Protection Overall Weight 15.4 oz Overall Length 12.2" Black
