The 3-9x50 Crossfire II Riflescope (Straight-Wall BDC) from Vortex Optics is a cost-effective yet durable variable power riflescope. The 3-9x magnification is ideal for close and mid-range hunting and target practice. A nitrogen purged and o-ring sealed aluminum housing is built to perform in driving rain and extreme humidity. This model of the Crossfire II is configured with a Straight-Wall BDC reticle and low-profile capped windage/elevation turrets. The wide 50mm objective lens features enhanced light gathering ability that is well-suited for performance in low light conditions. A fast focus eyepiece, fully multicoated optics, and generous eye relief make the Crossfire II a full-featured scope for sportsmen.
