Agreed, air-boats are noisy! Folks run them up and down the Platte River and they can be a bit distracting. Our local Boy Scout camp is on the south side of the Platte River near Fremont, NE, and the air-boats running at night are noisy enough to keep you awake if you have the bad luck of drawing any of the campsites on the bluffs above the river.
The original question arose from my recent purchase of two RAR Predators which come from Ruger with the barrels threaded for suppressors. I was surprised that there was enough consumer demand for a major manufacturer to offer factory threaded barrels in a whole series of regular production firearms. Other than deer herd reduction shooters, I've never seen anybody with a suppressor.
