If you’re looking for more power with a bigger objective lens then the 4X-16X50 is the perfect scope. Gathering 156% of the available light versus a 40mm lens you’ll run out of ammo before you run out of light. The KonusPro 550 takes the guess work out of hold over angles for even the most difficult of shots. The exclusive ballistic reticle coinciding with the most popular center fire loads today provides you with a system of reference lines for exact aiming points out to 550 yards. Lateral hash marks allow for precise leads of moving targets as well as compensating for strong crosswinds. The glass engraved ballistic reticle is unbreakable and the multi-coated optics are clear and bright. Parallax is removed thanks to the adjustable objective.
