Ideal when your red dot sight cannot be adjusted low enough to zero properly. The shim raises the rear of the sight to adjust the point of impact downward. -
1.0 Degree Taper
Precision-cut shim with a 1-degree taper and +/- .005 tolerance. -
Elevation Adjustment Aid
-
Thicker side at rear: Lowers the point of aim
-
Thicker side at front: Raises the point of aim
-
-
Durable & Universal
Designed to work across a wide range of optics and firearms—especially helpful on certain 1911 platforms. -
Quick and Easy Installation
Simply place between the optic and the mounting plate. Re-zero after installation.
What It Solves:
When users are unable to bring the dot low enough due to limited elevation adjustment—this shim lifts the optic slightly to provide additional downward travel for the dot, solving a common "maxed-out elevation screw" issue without returning or replacing the optic. -

worked as described
Installed a Vortex Venom on a Walther Q5 Match, and bullet impact was very low. Ran out of adjustment to raise point of impact. Put this shim on and it worked perfect, giving me plenty of adjustment to zero the red dot on target.

Exact fit for Glock 40 mos.
I bought this to go on a Glock model 40 mos. I had originally installed my Vortex Venom and did not have enough down adjustment to sight it in. I installed the 1 degree delrin shim and my adjustments are almost center for vertical now. Great product direct fit and solved my issues!

Easy to put on and worked as said for my red dot

Better than a piece of tin. Ha!
Was having trouble getting enough elevation adjustment on a Vortex Venom I had installed on a Walther WMP. This fixed the problem and was easier than sending the red dot back to Vortex. Of course, if I have problems down the line, then I probably should have done that first.

Solved my red dot issue perfectly.
Neede just a little bit of rise on my red dot and this was perfect. Fit as it was supposed to, and delivered the end result I needed.

5.0 out of 5 stars Just what was needed to zero in my venom
Elevation adjusting screw ran out of adjustment when trying to zero in the red dot. With the ADE shim plate that issue went away.

works great
I had to do minor fitting to my PSA Dagger. I had to use an emery board to remove a very small amount of material to the rear of the shim. It was just a little long for the cut on the slide. After this the holes lined up perfectly to the Vortex Venom. Now I can get it sighted in correctly.

5.0 out of 5 stars Allows zeroing my Vortex Venom
Helps to center the red dot on my Vortex Venom site. It had maxed the adjustment before installing this shim.

Perfect fix
Used this shim to raise the rear of the Vortex Venom on a CZ 75 SP-01 dove tail plate. Before,it would not zero, the adjust screw was at it's up limit. Now the up/down adjustment has plenty of adjustment between max up and down. Worked like a champ. If you're having the same problem, this will fix it and is worth the price. Thanks Ade Advance optics.

5.0 out of 5 stars Elevation Problem Solution
Recently I purchased a Vortex Venom red dot sight for my Ruger Mark Iv Lite. However, after mounting it on the pistol, I found it impossible to zero, as it ran out of elevation. In my frustration, I contacted Vortex and they suggested an ADE Advanced Optics shim placed between the mounting plate and the sight as a solution. Voila, my elevation problem was solved and my frustration ended.

Solved my problem
Just purchased a Vortex Venom Red Dot Optic for my Springfield XDM. Installed the Optic went to the range to zero in the red dot and ran out of elevation adjustment. Thought I would have to send my Optic back. I googled the issue and was directed to amazon. On Amazon they stated the ade shim would solve my problem. Fortunately I have Amazon Prime got the shin overnight free shipping. Took about 5 minutes to install Drove to the range and zeroed in the optic. Great solution to my issue. Problem solved.

Solve my Vortex Venom problems!!!
Bought a venom and tried it on my shotgun… shot 4-5” low with the dial maxed out. Tried it on my 22/45… shot dead on, but also with the dial maxed out. Tried this product and it fixed the problem! With it installed on my 22/45, I was able to back off the dial almost 2 full rotations = 50 clicks = 50 moa!!! Doing online research, I found this a very common problem with the Venom. I even contacted Vortex and the said to use a shim. Vortex should just include this shim with ALL their Venoms!
