3-9x is THE classic size for hunting scopes. The Droptine family has two 3-9x models, this one with a 40mm objective end, and one with a 50mm. Has the focus set at just 50 yards, making it a great choice for .22 LR ammo. The 3-9x40mm is compact and lightweight, with a nine times magnification that provides enough distance for most hunting situations.The simple, rugged reticle has holdover for precise shots at extended ranges. The low-profile turret is finger-adjustable. A separate eyepiece and power ring allow for flip-up lens caps.
