Suppressed CMMG mutant?

Thinking about getting a CMMG Mutant as a cheaper ammo alternative to 300blk as a dedicated 30 cal suppressor host.

Has anybody tried it yet?

I’ve never heard a suppressor on 7.62 Soviet. It’s supposed to be a lower pressure round than the 300blk saami spec for supersonic. How do they compare?
