M&P 9mm PC CORE - Viper red dot mount?

[baconz22]

Having a little challenge with my red dot. Searching the interwebs appears to mention an adapter plate for the Viper. I believe the slide on this 9mm Pro Performance Center is cut for an RMR.
Anyone have an idea or link to an adapter plate to securely mount this Vortex Viper?
Searched forums but couldnt find an answer.
Thanks!

First, you should verify if that's actually a C.O.R.E. model, or a regular one that had the RMR cut done by a third party.

If it is a C.O.R.E. then the mount should be modular and can be swapped out for the appropriate mounting pattern plate.

hmmm... 99% sure it is the CORE model.

CORE model should come with adapter plates; I have a Venom mounted on mine and used one of the plates included. IIRC Vortex uses the same plate as Burris Fastfire.
