The HELOS BTR 1-4.5x;24 rifle scope is specifically crafted for use in service rifle matches and AR platforms, catering to short and mid-range shooting scenarios. This scope is equipped with durable turrets that offer 23 MOA adjustment per rotation, ensuring precise targeting. It also features a true zero stop and revolution locking mechanism, along with fully multi-coated lenses. The revolution locking feature allows you to limit the upward adjustment of the elevation turret to one revolution from the zero position, while still providing a total of 23 MOA adjustment, which is more than sufficient for hitting targets up to 600 yards away. This eliminates any confusion about the number of turns on your elevation turret. The ATSR3 reticle is specially designed for service rifle matches, featuring a well-proportioned center circle that fits most targets, a center dot for precision aiming, and a horizontal line for compensating for wind drift.
