C. Muzzle Devices: Flash hiders, compensators, and muzzle brakes are permitted.

That's the inclusive list of allowed muzzle devices. I don't see suppressor on there.
I don't know how timers would work with those anyway. Even a non suppressed PCC is sometimes an issue to get the timer to hear all the shots.
