Leupold’s Mark AR MOD 1 scopes have variable power settings for fast, accurate engagement of close and distant targets. Perfect for AR-15s because the P5 BDC dial aids in precise aiming with .223/5.56 NATO loads, though these scopes also work very well on traditional bolt-actions, too. Leupold’s Quantum Optical System™ and proprietary Multicoat® lens coatings combine to deliver optimal brightness, contrast, and edge-to-edge clarity in all light conditions. Purged with a unique Argon/Krypton gas blend, these scopes are waterproof and highly resistant to damage from shock. Duplex/Fine Duplex reticles are standard crosshair-style reticles. Aluminum tube, matte black finish, 1" O.D. Illuminated models use a CR-2032 battery, included. AO - Adjustable Objective.
