I've dabbled with my new AAC M4-2000 Mod 08 suppressor on a LE6920 since getting it last February.
It's nose heavy, but quiet. About 132 decibels
Every October our club has a Zombie shoot (head shots only) and one of the bays has a shoot house that is totally dark.
Moving through the shoot house is straight forward movement with no side shots. The RO is directly behind you with the timer and a hand held or weapon light is required.
Well my setup ran great. My heart was racing and I didn't even notice the extra weight at the end of the barrel. Zero muzzle flash. My hit ratio was good too, using an CompM4s red dot.
Our club has sunup to sunset hours, so other than this event there is no other time to shoot in darkness. Quite an experience
Not me, but here is the Zombie House
