This optic shim will provide a 1.0 degree angle to either raise or lower the elevation on your optic. If you are having trouble gaining or losing elevation to zero, this will give you the ability to get more movement from the elevation screw. The shim is placed between the adapter and the optic. Each shim is compatible with one of the below footprints.

Optic Shim Compatible footprints (each shim has a different footprint):

• Trijicon RMR/SRO – Holosun 407/507 C, 508 T
• Vortex Venom, Viper – Docter – Burris
• Shield RMS/RMSc – Holosun 407/507 K – Sig Sauer Romeo Zero – Leupold Delta Point Pro – Crimson Trace CTS 1250

Features:

• Optic Shim is made to fit between the red dot and the mounting plate.
• Scope base shims Tolerance +/-.005 Taper 1.0 degree
• Depending on the handgun,  some handguns need a 1 degree shim to give extra range of elevation across a wide range of firearms. Should you feel any resistance from the mechanism whilst zeroing the elevation please fit the shim between the sight and the mount with the thickest part at the rear.
• While zeroing the red dot sight, the elevation screw can extend all the way to the end and is maxed-out. The location of the illuminated dot is still TOO HIGH, the user is UNABLE to adjust the dot LOW enough to zero. This shim will raise the optic to help user to move the illuminated dot higher to the location to zero.
• 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.
