I have enough experience with this to avoid an unsuppressed rifle, particularly a SBR, indoors like the plague. A unsuppressed Mk18 sucks to shoot inside a structure even with ears on.

Even a pistol is very loud. I once shot a 1911 out of a Toyota with no earpro, and I initially thought my radio coincidentally died, because the chatter went silent for a moment. Or so it seemed.

Ron3, I’m not really concerned that an attacker won’t have a sound suppressor. 5.56 reliably suppresses enemy weapons down to ambient levels, and if I’m unsuccessful at that, then the bullets coming my way represent a much greater hazard than their muzzle report. That’s kinda the point of being armed in the first place.
