Help identifying T81 Scope Mount

[Poker_Police]

If someone knowledgeable wouldnt mind... a T81 that i bought has this side receiver mount - if possible id like to find out what it's compatible with. Thx for any insight!

It's an AK rail. It should be compatible with most Russian side-mounted optics.

I assume this means it will work with the Rs regulate or leapers utg pro?
Appreciate it

SVD mount optics will not work. AK and universal mounts will. I believe RS and UTG are universal.
