Perfect fit for my RMSc red dot sight
Works great and fitment for RMSc footprint was spot on. Quality and finish are excellent as is most Monstrum products. Installed and mounted easily. Durability still needs to be tested as I haven’t fired my pistol yet. Compatible with standard picatinny rail. Solid value at this price point, would buy again.

Solid Mount for a Ruger 10/22
I picked this up for my Ruger 10/22 so I could reuse a Sig Romeo RS red dot that I already had sitting around. Installation was simple, fitment was solid, and it locked up securely without any issues. It does sit a little higher than I’d personally prefer, but once I got it sighted in, it worked great. The added height hasn’t caused any real problems, and it’s been a nice way to give an extra optic a new purpose instead of letting it collect dust. Overall, a solid mount that does exactly what it’s supposed to do.

Quite nice! Couldn't be happier with it.
This is a really nice little picatinny mount for an RMSc red dot. It comes with three different length mounting screws as well as keys to drive those screws. The fit and finish of the mount is perfect - it grabbed my Ruger factory pic rail like grim death and my Crimson Trace RAD Micro Pro Carbon sight popped right on to the mount and didn't move a whit after installation of the appropriate screws. Solid. And for the price? $13 and delivered overnight? Man, we are living in golden times . . .

Quality
Fast shipping and the price is awesome for what you get. Bought it to mount a red dot to a pic rail on a 22 pistol. This mount is more than capable of that. Fit and finish is really good. Would recommend.
