Designed for short- and mid-range AR duty and service rifle matches, the Helos BTR 1-4.5x Scope features advanced fully multi-coated optics, illuminated reticle, and innovative turrets with true zero stop and revolution locking. The revolution locking feature limits the inchup inch adjustment of your elevation turret to within one revolution of your zero position, while still providing 23 MOA of travel per rotation-more than enough for targets at 600 yards. The ATSR3 illuminated reticle features a large illuminated circle that's the ideal size for service rifle match shooting. The center dot helps you get locked in on more distant targets, and the 2 MOA hashmarks provide ideal windage and holdover info. For short- and mid-range work, the Helos is head and shoulders above the competition.
