(All trademarks mentioned belong to their respective owners. This optic shim is manufactured by ADE as a mounting accessory compatible with the above optics.)
Product Description:
This optic shim is designed to be installed between your red dot sight and its mounting plate. With a precise 1.0-degree taper and +/- 0.005 tolerance, this shim provides critical elevation compensation when zeroing optics—especially on platforms like the 1911 that may have limited elevation adjustment.Why You Need It:
On certain pistols, users may find that the red dot’s elevation screw maxes out before the dot can be lowered enough to zero the optic. Rather than returning the optic as defective, this shim can raise the rear of the sight, effectively lowering the dot in the window and allowing proper zeroing.
Installation Tips:
-
To lower the dot (most common use): Position the thicker side at the rear (toward the shooter).
-
To raise the dot: Position the thicker side at the front (toward the muzzle).
If you encounter resistance when adjusting elevation, the shim may be required.

Just what I needed
Quick delivery, perfect fit. I did not initially have enough elevation for my Leupold Deltapoint Pro but this product took care of that problem.

Perfect for my red dot! Brought it into range for sighting in…
The 1% wedge worked perfect as not to max out my elevation adjustment on the Holosun 407k x2

Works as it should

This Worked Great
Not much of a reviewer but this shim worked great on a Hex Wasp. Although the Wasp was working fine, I had it completely maxed out on elevation and was still shooting low with my RD right on top of my front sight. Now, shooting on target with RD where I wanted it to be originally. Had to cut down the shim a bit to fit the cutout on the slide but all was easy to do and holes in shim matched perfect with hole patten in the slide. Super simple.

Works Well
Not the most fun to spend money on a shim, but when you need one it's nice to have a good one on the shelf and available. This fit well and is easy to install. Much faster than trying to make your own precision shim.

Good fit, quality
This 1 degree wedge took care of my situation and the fit between the sight and mount is very good, almost unnoticeable. Sight used is the Holosun 507 comp
