The TopTactical Scope Engineering Level is the simplest and most accurate scope leveling system ever created. Misaligned crosshairs can compromise the precision of your shots, especially at long ranges. Crooked crosshairs not only make your scope adjustments unreliable but can also turn zeroing your rifle into a frustrating and costly experience. Unlike other leveling devices that advocate leveling to the top of a scope base, the Scope Engineering Level system levels your scope to your receiver, ensuring accuracy.This system works efficiently, allowing you to level your scope as you mount it on your rifle. The magnetic base in the rifle level bridges the bolt raceway, enabling you to position your rifle perfectly level. Afterward, leveling the scope, tightening the rings, and completing the job take only minutes. Compatible with virtually any bolt-action rifle, it is also adaptable to other designs. Save both time and money with the TopTactical Scope Engineering Level system — a straightforward and precise solution that ensures your scope is perfectly leveled to the receiver.
