The Citadel 3-18x50 LR1 riflescope is designed for medium-to-long range shooting, competition shooting, law enforcement 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 ¼ 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.
