The Helos BTR 1-4.5×24 rifle scope family is specially designed for service rifle matches and AR platforms with short and mid range applications in mind.  The scope is loaded with robust turrets that have 23 MOA travel-per-rotation, true zero stop and revolution locking feature,  and fully multi-coated lenses. The revolution locking feature limits the Up Adjustment of your elevation turret within one revolution from your zero position, while still providing total 23 MOA adjustment that is more than enough for your target at 600 yard. This feature eliminates any second-guessing you might have on which turn you are at on your elevation turret.  The ATSR3 reticle is specially designed for the service rifle matches with the center circle at right size that fits most of your targets and the center dot for precision and horizontal line for wind hold over.
