About this item

  • 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.Position the thicker side toward the end to lower the dot. Position the thicker side toward the front to raise the dot.
  • Fits: Trijicon RMR/SRO, Ade Advanced Optics, RD3-019, RD3-020, RD3-023, Holosun HS407C/HS507C/HS507T and
  • 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.
  • 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.
  • 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.


Position the thicker side toward the end to lower the dot. Position the thicker side toward the front to raise the dot.

This product is overpriced for what it is, but it does work well.

Does it’s job but the first one came broken. I’d look at buying the metal version instead of this one. The fitment was good and it does it’s job, it’s just very brittle.

Simple fix for a known issue. A bit pricey for a single piece of thin polymer shim that acts as a wedge. Still maxed out from a 25 yard zero and would still need an additional shim due to an adapter plate for the slide. For an offset sight rifle setup I would have to buy maybe at leas three to four to get zeroed. Works well but a set for the price will make it cost effective.

Item arrived quick enough. The problem I had was that the holes were slightly off for my slide. I forced it into place causing the shim to split. Its covered up and does its job so it does work.
