• Optic Shim is made to fit between the red dot and the mounting plate. Depending on the handgun, some handguns need THIS 1degree shim to give extra range of elevation across a wide range of firearms (such as the 1911). Should you feel any resistance from the mechanism whilst zeroing the elevation please fit the shim between the sight and the mount. Position the thicker side toward the end to lower the dot. Position the thicker side toward the front to raise the dot
• Position the thicker side toward the rear of the slide to lower the dot. Position the thicker side toward the front of the slide to raise the dot.

• What it does? While zeroing the red dot sight, some users turned the elevation screw all the way to the end that can no longer turn(screw maxed-out), the location of the illuminated dot is still TOO HIGH, user is UNABLE to adjust the dot LOW enough to zero. Instead of returning the "defective" red dot, this shim will rise the optic to help user to move the illuminated dot higher to the location to zero. Scope base shims Tolerance +/-.005 Taper 1.0 degree.
