Combine optical features you need with the platform you prefer and you have the Nikon® P-TACTICAL 3-9x40mm Rifle Scope. The multi-coated optical system reduces reflection to maximize light transmission, brightness and contrast. The MK1-MOA reticle provides ranging, holdover and windage corrections. Paired with spring-loaded windage and elevation knobs with instant zero-reset and directional indicators you get an easy method for performing in-the-field adjustments. The 1" aircraft grade aluminum tube with Type-III hard anodized finish provides shockproof construction shrugs off the recoil of hard hitting calibers.
