Combine optical features you need with the platform you prefer and you have the Nikon® P-TACTICAL .223, 3x32mm Rifle Scope. The multi-coated optical system reduces reflection to maximize light transmission, brightness and contrast. The platform-based BDC Carbine reticle features open-circle aiming points and hash marks at 200, 400 and 600 yards. 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 provides shockproof construction to shrug off the recoil of hard hitting calibers.
