Precision minded shooters looking to maximize the long range accuracy of the Malcolm 6X Long scope need a reliable and repeatable method to consistently adjust the elevation.
Due to the original design of the long scope, you would need to manually loosen and move the scope up or down in the rear mount to change the point of impact. With access to only a vernier scale on the rear mount, this method of adjustment is not consistent and is subject to human error.
With the Fine Elevation Adjustment Set installed, the shooter can simply turn the knurled thumbscrew to vertically adjust the point of impact. Rotating the screw clockwise will move the point of impact upwards. Rotating the screw counterclockwise will move the point of impact downwards.
