Ade Advanced OpticsUniversal Plate - Converting Trijicon RMR/SRO Footprint to Vortex Venom, Burris Fastfire, Shield RMS - RMR Mounting Plate Adapter Converter for Red Dot Sights

Garbage plate. Holes were completely out of tolerance. Holes for RMR posts do NOT line up so it doesn’t actually fit on an RMR footprint with posts. Threads are not in spec either.

Bought for my G19 to attach an optic, because the optic ain’t come w no plate. No. That would be too easy. Instead I gotta get 9 different plates. None of which place the optic where I want it. So you would think “universal” right?Got more holes than Swiss cheese in it. One of em GOTTA work. No. Sadly no. 🤣

Got this for a third party Glock G34 sized slide with an RMR cut. Hole alignment was good both for the slide and the optic I need to mount. Good up to this point. The photos show a slide with posts which mine has; however, the adapter will not fir over the posts. I did notice as well that the adapter would hang over the left and right edges as well had it fit over the posts. I think this would have been doable, but it would have looked a little off.

This adapter plate is well made. Worked perfect on my Glock build with a Vortex Viper red dot. The picture of the plate shows everything in black it actually comes in aluminum silver color so be prepared for that if you're hoping for black.

Even though I have an almost identical slide to their pictures, the adapter plate does not work with my ninex19 slide cut for an RMR. The holes drilled out for the recoil lugs in the slide do not line up with the holes machined in the plate, and they are machined a bit to small to accept my slide regardless. I am sure I could make it work with a drill, but I'd rather just try out one of their optics for the same price instead. Bottom line: there really isn't any good cheap way to replace an RMR

Slightly disappointed, first time using it. Tightening screws for a sig romeo 0 to manufacturer spec of 9in/lbs, And the threads inside the plate let go.

The other reviews are accurate about this POS not fitting properly. Don’t buy this part.

I have a custom glock side that has an rmr cut. Based on the description, the adapter should fit an rmr cut and compatible with a vortex venom. The adapter plate fits the rmr cut, however it's not compatible with vortex venom. It's a waste of money. DO NOT BUY.
