Review: Exactly what I needed - This was exactly what I needed. Due to the cut on my slide, I was making out my optic and still unable to get on target. This gave me the perfect amount of angle to get on target with some extra adjustment left over. Due to its size I did have to cut it down to size to fit the rmsc footprint.
Review: Slightly long and holes don't line up perfectly to RMSc - 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.

## Features

- ELEVATION CONTROL FOR SIGHT ZEROING – Precision 1° Delrin shim fits between your red dot optic and mounting plate, allowing fine-tuned elevation adjustments. Flip orientation to raise or lower the dot, solving alignment issues during zeroing without returning your optic.
- SAVE YOUR SIGHT, DON’T RETURN IT – If your red dot maxes out its elevation adjustment and still sits too high to zero, this precision shim offers a practical fix. By slightly raising the optic, it allows the illuminated dot to move lower within your sight picture—no need to return a working red dot as "defective."
- WIDE OPTIC COMPATIBILITY – Fits Holosun 407K/507K, EPS, EPS Carry, Shield RMS/RMSC/SMS/RMSW, ADE RD3-018 SPIKE, RD3-021 NUWA, RD3-030 Apollo, Romeo Zero, Delta Point Pro, JP Enterprises JPoint, and Sentinel. Not compatible with RMR, SRO, Docter, Venom, Viper, Fastfire, or ADE RD3-006/009/012/013.
- ELEVATION FIX FOR HARD-TO-ZERO DOTS – Some optics can’t adjust low enough to zero, even when the screw is maxed out. This 1° delrin shim lifts the optic just enough to bring the dot into alignment. Taper: 1.0°, Tolerance: ±.005 for precision correction.
- EASY INSTALLATION WITH FLEXIBLE FIT – Installs between red dot and mounting plate in minutes. Position the thicker side toward the rear of the slide to lower the dot. Position the thicker side toward the front of the slide to raise the dot. If center screw holes are slightly off on some optics, simply widen the hole as needed for a secure, flush fit. No need to return or replace your sight—just fine-tune and go.

### ⭐⭐⭐⭐⭐ 407k
*by K***R on January 11, 2025*

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.
