Offering a wide magnification range for close to mid-range shooting, the Citadel 1-6x24 combines impressive performance with a stealthy appearance. Designed with real shooters in mind, the Citadel 1-6x features a second focal plane BDC reticle calibrated for 55gr 5.56/.223, red reticle illumination for contrast against targets and low light shooting and fully multi-coated optics. Capped, low profile turrets protect zero and add to the Citadel’s no-nonsense, subdued appearance. A single-piece, 30mm tube and aircraft grade aluminum construction make the Citadel extremely durable and IP67 waterproof. Ideal for a variety of firearms, including ARs and bolt actions rifles, the Citadel 1-6x24 CR1 includes flip up lens caps, a handy throw lever and one CR2032 battery.
