    Grossly over priced.

    Posted by George W. Plesa on 4th Jul 2025

    Grossly overpriced but it does work. I was unable to get more elevation out of my Holosun 507C mounted on a Glock 23. I put this under the sight with the thicker end to the rear and now I have elevation to spare.

    Fits either direction

    Posted by readsalot on 4th Jul 2025

    Although the listing indicated this is primary used to shim the sight with the thicker part of the shim under the rear of the sight (to lower the dot further), I needed to do the opposite. My gun was shooting too high and I need to shim the front to raise the dot. The shim design does allow placing the thicker end under either the front or rear part of the sight. It worked well for me and allowed me to zero my sight.

    Fixed the adjustment problem on a pistol optic.

    Posted by Customer on 4th Jul 2025

    I needed adjustment for the optic sight on a pistol. I ran out of elevation, so I bought this shim from Ade Optical on Amazon. It arrived quickly, and worked perfectly, putting the optic right where it needed to be.
