The BSA Sweet .22 Target/Hunting Rifle Scope is part of the new BSA Sweet Series of scopes that utilizes military-grade trajectory compensation technology to improve speed and accuracy for both target and varmint hunters. These scopes are known for their ability to compensate for the trajectory of specific grain weights for .22 caliber bullets. The BSA Sweet .22 Target/Hunting Rifle Scope features a quick-change elevation and windage turret system that allows you to quickly return to zero at the touch of a button. BSA Sweet Series scopes also include side-adjustable parallax control settings of 7.5 to infinity.
