Introducing a low profile, scope mounted, precision
level that provides a convenient solution to the often ignored sighting
problem confronted by any rifle shooter wishing to achieve high or
ultra high accuracy. Various solutions for making sure that the
intended aiming point and the projectile trajectory lie on the same
vertical plane go back to before Civil War times. Thus, while certainly
not revolutionary, this product is meant to be, besides being precise,
easy to use and conveniently there when needed. Once mounted the level
adds only 5/8 of an ounce, is no more obtrusive than the top of the
usual scope mounting ring, and appears to be an integral part of your
scope.
Present barrel, bullet, and scope technology
allows shooting accuracy of better than ½ minute of angle (MOA)
and consistency of better than 1/8 MOA to be quite achievable from
a steady rest, but not over any distance with a significant bullet
drop if the rifle bore and scope center line plane is canted. You
will find when using only surrounding references, especially if out
in the field, that setting your scoped rifle up with a vertical angle
error of less than plus or minus 2° is quite difficult. This ±2°
error from vertical for the rifle bore - scope plane equates to a
1 inch horizontal spread for each 14 inches of drop. But, using a
precision scope mounted level makes it easy to hold this vertical
angle error to less than 4 MOA as you set up for the shot or shots
from your rest.
The scope mounted sighting levels are produced
in two sizes to fit either 1 inch or 30 mm body tubes. They are CNC
machined from aluminum, fitted with glass spirit levels, and come
anodized either matte black or bright silver. When mounted, the spirit
level can be easily seen at any angle from above or behind.
Mounting of the level can be anywhere along
the main scope tube that the user wishes. But, for the accuracy possible,
it needs to be clamped on precisely level at the same time that the
scope center line is exactly above the rifle bore center line. To
assure this and make it quick and easily done, each level is shipped
with a precise alignment/leveling fixture to be used across either
scope ring during the mounting procedure. This alignment/leveling
fixture also makes leveling your scope crosshair much easier and precise.
