Ade Advanced OpticsOptics Shims Elevation Shim to give Extra Adjustment Range for Trijicon RMR, Holosun 407C/507C/508T, Swampfox Justice/Liberty/Kingslayer Red Dot Sight

Sounds like it works for most people. Unfortunately it didn't fit my slide cut and rmr plate. Trimmed it up a bit, and it added elevation for my 507c. I wish I had ordered 2 to add more, but I'll just deal with the slightly off zero situation.

Easy to install. Gives me the ability to zero my red dot. I will buy again if I need it.

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.

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.

I could never get enough elevation adjustment from my RMR mounted on my CZ P10-C to zero at close ranges like 5 to 10 yards. Impact was always too low. With this inexpensive but quality shim installed that problem was cured. Just remember the thick part goes to the rear of the optics cut between the adaptor plate and the optic. Easy to install does the trick

One doesn’t always need a shim when mounting an optic sight. But, for those occasions that require one, this one works great.

Had installed a red dot on my G3C and couldn't get the zeroing complete because dot was way too high. Thank goodness for this delrin shim. Two mags through it and it's up and running fine.

This solved my problem with my SRO loosing dot on the bottom part of the glass because I had to adjust my elevation way up. Great product !
