Situated on the high ground of close-to-long range optic performance, Citadel Riflescopes include affordable first-focal-plane, long-range capability and second-focal-plane tactical solutions. Citadel series optics are perfect for precision shooters, multi-gun competitors, hunters, and yes, most definitely, LEO's who demand and deserve peace of mind reliability.
Sightmark's line of Citadel Riflescopes are designed to help professional, competitive and recreational shooters climb to the top of their game with impenetrable confidence and win the day with feature-rich, premium performing optics. All Sightmark Citadel riflescopes boast 30mm single-piece, aircraft-grade 6061-T6 aluminum tubes; premium, fully multi-coated glass; fine-etched, red-illuminated reticles; lens covers; throw levers; IP67 waterproof, dust-proof, fog-proof and shockproof reliability.
The Sightmark Citadel riflescope is equipped with a side focus dial that is used to eliminate parallax and finely focus the image. Parallax occurs when the image of the target does not focus at the same optical plane as the reticle inside the riflescope. When parallax is present, the reticle appears to move over the target when the shooter's eye is not centered to the eyepiece. Adjusting the side focus dial properly will eliminate parallax.
The Sightmark Citadel riflescope has finger adjustable elevation and windage adjustments with audible clicks. The Citadel 1-10x24 has capped turrets, the turret covers must be unscrewed in order to make adjustments.
The CR1 reticle is a second focal plane, minute of angle (MOA) reticle. This reticle is calibrated for 5.56x45 / .223 Rem. 55gr FMJ ammo. The reticle was designed for a 100 yard zero. At 6x magnification, the 1 MOA aiming dot is used to engage targets from 0 to 200 yards. The reticle consists of a circle dot design for quick target acquisition in close range engagements. At 1x magnification, the outer circle will cover approximately 15 inches of a target at 25 yards. This is nearly equivalent to shoulder width of IPSC targets. Below the aiming dot, holdovers can be used to determine range of IPSC targets and perform ballistic holdovers out to 600 yards. Finally, the main horizontal subtension is scaled in 5 MOA increments (at 6x) and can be used for leads for moving targets.
The Sightmark Citadel riflescope eyepiece is designed to rotate to adjust for diopter. Diopter is the measurement of the eye's curvature. By rotating the eyepiece, the diopter is adjusted to properly match each person's vision. If the reticle does not appear clear, crisp, nor sharp, rotate the eyepiece until the reticle becomes clear and sharp. This adjustment should stay the same unless the riflescope operator changes.
