This Nikon ProStaff 4x32 Nikoplex (6718) is designed to not only live up to the reputation of its popular predecessor, the 4x32 Rimfire Classic, but to set the performance bar even higher. Just sight in as usual, then lift the spring loaded adjustment knob, rotate to your “zero”, and reengage. Field adjustments are now as simple as dialing in your subsequent ranges. Positive click reticle adjustments get you zeroed in quicker and maintain your setting even with heavy recoil. Keeps your brow safe even with the heaviest recoiling cartridges, lightweight rifles, and severe shooting angles. It’s no wonder hunters and plinkers are so excited to get their hands on this next generation riflescope.
