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 with the thickest part at the rear. 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. Also fits Riton X3 Tactix PRD, ADE RD3-011, Swampox Kingslayer/Liberty/Justice. The shim might need to be trimmed to the shape to match some of red dot brand mentioned above. Fits: Trijicon RMR/SRO, Ade Advanced Optics, RD3-019, RD3-020, RD3-023, Holosun HS407C/HS507C/HS507T and. Do not return your "defective" red dot that can't adjust the illuminated dot high enough to zero. This optic shim solves the problem by raising the red dot higher to zero. Optic Shim is made to fit between the red dot and the mounting plate.
