The Konus 7277, better known as the KonusPro 550, simplifies complex shooting equations, making challenging shots more manageable. Its specialized ballistic reticle aligns perfectly with the prevalent center fire loads used currently, helping you to pinpoint exact aiming points up to 550 yards. For added accuracy, it features lateral hash marks to precisely lead moving targets and compensate for significant crosswinds. Its ballistic reticle, etched onto the glass, is virtually indestructible. Also, the optics are coated multiple times, assuring clarity and brightness like no other.
