Ade Advanced Optics Optics Riser/Aluminum Elevation Shim to give Extra Adjustment Range for Holosun 407K/507K, Shield RMS/RMSC/RMSW/SMS, ADE RD3-018 Spike Handgun Reflex Red Dot Sight

Worked like a charm with my 407k and my Tisas 2011 patern pistol.I did have to trim the back of the shim.Note: if you need to trim stay away from the front where the lugs are.

This should be able to be used as -1 deg or +1 deg but the overall length was too long for the Shield Plus Factory RMSc Optic Cut.The Shield Plus has a .5 - .75 deg downward slope causing some red dots to max out elevation. I was hoping to use this shim as a +1 deg shim to even out the Shield Plus' downward angle.I had to trim the overall length and enlarge 2 holes but it still didn't work for the red dot I wanted to use which is the EPS Carry.The EPS carry footprint didn't work with this shim and even if I got it to fit, the posts of the optic were completely covered (shim + optic plate were too thick) and thus not able to function...meaning all the stress of recoil would be transfered to the 2 screws rather than the optics posts.If you don't care about the posts fitting under the red dot properly and don't mind mounting the red dot by just the 2 screws, then maybe give this a try but your screws may end up shearing off due to the recoil of the pistol.On a side note the new revised and improved Vortex Defender ccw red dot mounts (direct mount) perfectly to the Shield plus and gives plenty of elevation adjustments.

I could not find any plates for the C-more RTS/STS. The Vortex Razor comes with an adaptor plate. Luckily I did not need to use it.I took adaptor plate and aligned the holes with the various ADE plates on my phone. This one appeared to be closest. When it arrived I tested the ADE plate fit in both directions. The holes for the screws and pins aligned. The pins on my mount were long enough to reach the holes on the dot.This plate’s footprint is smaller than the the red dot, it will not look flushed against the edges. Once torqued down it works fine.

Did not fit my weapon well enough, but since this is made out of thin plastic I was able to cut it a bit and relocate the holes easily with scissors. The thickness of the material was perfect though it was mainly the width that was not right for my weapon. I was able to solve a gap between the slide and SIG RomeoZero that was cause by the screws that came with the Romeo being half a millimeter too long. This gap was of course enough to dislodge the battery and the Romeo would turn off after every round I fired. This problem no longer happens using this spacer with some modifications.

Pretty nice optic plate. It’s a little thin, and I was expecting it to be about 3x it’s thickness. Fits super good with any RMS or RMSC optic.

The product did what it was supposed to do. No complaints at all about it. The company did what it was supposed to do but using Amazon as a delivery system has a lot to be desired.

Product says that it should be aluminum and its plastic. Doesn't fit my shield plus unless I trimmed the ends and I'm not doing that. No thanks.

That little .040 of thickness made a difference in the maxed out elevation adjustment of myred dot.
