Compatibility:This rifle scope level is used on 30mm scope tube for the most precise long-range shooting
Essential:We use a 30mm scope bubble level to make sure if the scope is completely vertical, which can eliminate potential errors due to the shooting tilt effectively
Precision:The fluid flows smoothly and the bubbles move quite sensitively. Even a little tilt can cause the bubbles to move. With a calibration distance of only 8mm, this scope mounting kit will be more accurate to determine if tilted
Convenience:Equipped with allen wrench and screws, this scope leveling kit mounts quickly and easily to the scope tube
Compact:Small size and light weight, only 0.15 pounds. EZshoot anti cant scope level won't block your view while shooting
