Sightmark Citadel 3-18×50 LR1 Riflescope
The new premium Citadel 3-18×50 LR1 riflescope is designed for medium-to-long range shooting, competition shooting, LE and hunting. The Citadel features a 6x optical system, a fully multi-coated lens, exposed locking turrets and a red illuminated reticle with 11-brightness settings. The first focal plane reticle means the size of the reticle remains the same in any magnification and holdovers and range finding can be performed. The new reticle, LR1, is a 1/4 MOA reticle allowing each click adjustment to move the point of impact of an inch at 100 yards. The riflescope is crafted out of a single shockproof aircraft grade aluminum 30mm tube and is IP67 waterproof and dustproof. The optic comes complete with flip-up covers, a throw lever to adjust the magnification with ease and a sunshade.

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.
Windage and Elevation Adjustments
The Sightmark Citadel riflescope has finger adjustable elevation and windage adjustments with audible clicks. The Citadel LR1 have locking, pop-up turrets. These turrets must be pulled up to disengage the locking mechanism. Once disengaged, adjustments can be made. When adjustments are finished, the turret can be pushed back down to lock the adjustment
The LR1 riflescope uses a Minute Of Angle (MOA) reticle and adjustments. The reticles are first focal plane, thus will grow in size as magnification is increased and vice versa. The advantage is the dimensions of the reticle will be true at any magnifications. The reticles can be used to determine target range and perform shot holdovers for wind/drop compensation accurately at any magnification. The vertical and horizontal MOA scales are scaled in 2 MOA increments. The top, left, and right end of the vertical and horizontal scale are scaled in .5 MOA increments. The reticle’s drop lines contain a series of reference dots for quick windage holdovers in 1 MOA increments. Finally, the aiming crosshair is .12 MOA.
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’s operator changes.
