Ade Advanced Optics Red Dot Elevation Delrin Shim – Optic Riser Plate for RD3 Series, Hex Dragonfly, Mini Shot, Tempus – 1° Adapter Plate for Sight Zero Correction – Precision Fit Shim for Red Dots

This shim worked very well for me on a doctor plate installed on a 1911 commander size. The green dot I installed ran out of elevation adjustment. The shim has a 1 degree raise at the back to help with the elevation. The whole setup is working great. ADE offers to send the shim for free if you buy their optic but I didn't want to wait.

So I originally bought the Venom for my Mossberg 590, since it came with a Picatinny/side saddle attachment but unfortunately the sight did not adjust enough, and shot placement was low, even at max settings. This shim fit perfectly on the mount that came with the optic, no modifications needed, and functioned exactly as described. I haven’t had a chance to take it out yet, but it does fit well, and appears to line the sight window up slightly better than without it. Will see in a week when I have a chance to take it out. But for a stock vortex venom, it fits.

I was having a hard time getting my red dot lowered enough to begin sighting in on my M&P Shield Full Frame pistol, so off to Amazon I went. After doing a quick search for “pistol sight shim”, the Ade shim popped up near the top of the search feature. So I figured that I might as well give it a shot since it cost like $10. Shipping was quick; delivered two days after order, like most prime products. The product feels like plastic…but I believe it is still metallic as the battery for my sight is operational and could only conduct with a metallic object. I didn’t have any issues with mounting like some of the other complaints, everything seemed to line up perfect. The only issue I had was figuring out what screws to use that came with my mounting plate, as the normal ones weren’t quite long enough once I added in the shim. I did have an extra set of screws that fit perfect so it came together pretty well. Once tightened down, everything looks good and feels tight, which is what anyone would want when using precision optics mounts. My only gripe, if you could call it one, is that it just “feels cheap” due to it being pretty flimsy…but hell, what can you expect with with a 1 degree shim? If you’re on the fence, just make the decision to get one. It worked out very well for me and should for you as well.

It was what I needed to add some elevation to my red dot. Good price.

After a few weeks of researching shims I decided on this one. I was pleasantly surprised with how it bolted on my pistol. Everything lined up perfectly and I am well pleased with the product.

Like many reviews, this shim did not fit correctly for the mounting plate and ADE RD3-12-Pro red dot optic. To make it fit, I had to elongate the mounting holes (Dremel tool) which were quite a bit off. Once mounted, the shim serves it purpose for aligning the optics to my firearm. However, at $12 for a piece of plastic with incorrectly spaced alignment holes, I'd barely give this item 3 stars.

After reading the reviews I thought I would take a chance. Well, I got burned! This product is garbage. The holes DO NOT line up at all. If you try to enlarge them the delrin cracks. How can the holes be off by that much? The mount pictured is a EGW made in the USA Red Dot mount for Springfield. The new dragonfly HEX Red Dot needed a shim so I didn't have to run the elevation screw to max setting. Advice, buy the UM Tactical shim. I used them before and they fit perfectly without ANY modifications. Unfortunately, they were back ordered and I needed a faster delivery. Don't make the same mistake I did...

If you have an optic that has maxed out it's elevation this is a perfect solution to allow you to zero out your optic.
