BDC Carbine Reticle: Developed specifically for the trajectory of the .223 Rem/5.56 NATO round with 55-grain polymer tip bullet, the new BDC Carbine reticle provides a 200 yard crosshair with "hash marks" at 400 yards and 600 yards.

Fully Multicoated Optical System: Provides up to 98% light transmission and maximum brightness from dawn to dusk.

100-yard Parallax Setting: Eliminates parallax for precise shooting.

Generous, Consistent Eye Relief: Keeps your brow safe—even with the heaviest recoiling cartridges, lightweight rifles, and severe shooting angles.

Precise, 1/2" Hand-turn Tactical-Style Turrets: Positive click reticle adjustments get you zeroed in quicker and maintain your setting—even with repeated recoil.

Zero-Reset Turret Feature: To simplify field adjustments, Nikon has integrated this feature into all new riflescopes. 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.

Waterproof/Fogproof: Nitrogen filled and O-ring sealed.
