There is rumoured to be a room where M80s are run at ungodly power levels occasionally. I'm bringing my hearing protectors and earplugs (good for about 35 dB together, I think, enough that you don't really notice handguns going off beside you )

M60ti, VP180, QS8, M2ti, EP500, PC-Plus 20-39
M5HP, M40ti, Sierra-1
