[Overpaid Slacker]

No doubt, the blast wave is impressive. There's a one-stall enclosed space at the range (3 walls are enclosed, with windows -- the wall facing downrange is open, obviously). The friend who owns the M82 said "no way; we'd blow out the windows" when his bro suggested shooting from in there. I laughed. Until I stood "next to" the gun (though out from under the roof!) when it was fired. The concussion blew the door to that small enclosed room open from 10' away. It woulda blown out the windows.

I'd love to fire a MK-19, but I doubt it'd be cooler than the M82A1 experience.

True about the finger, but I did ensure it wasn't loaded, and it was pointed down a "live" range (ie nobody out there changing targets, etc.)
The idea of an intentional hipshot is amusing -- this thing is freaking heavy, and all the accuracy designed in to weapon would be useless "from the hip."
