Real Avid Level Right Pro helps to level a reticle, a task that is critical to long range accuracy. For longer shots a canted (or unlevel) reticle will pull or push the bullets trajectory off of vertical center. It gets worse the further the distance increases. A level scope means that the reticle (crosshairs) will be perfectly aligned with the rifle bore. Balancing small levels on a scope turret and gun receivers has been a commonly accepted practice for years. Not only is this a clumsy process, it’s wrong. The turret on most scopes is not perfectly aligned with the reticle (crosshairs), so even if the turret is level to the gun, the scope may not be. Level Right Pro changes all that by simplifying scope alignment in 4 easy steps. Accurate and intuitive, this time saving instrument quickly aligns the actual scope reticle to the horizontal gun plane (regardless of turret alignment), which is key to the long-range accuracy of your rifle. Level-Right Pro helps you quickly and confidently mount a scope for maximum accuracy.
