What do you think about suppressors on AR's for self defense?
Myself, I think a suppressor is mandatory on a AR that's going to used indoors.
I have a 12" suppressed AR as one of my house guns because it's short enough to handle but the suppressor takes away the disconcerting, obnoxious concussion from 5.56 in confined spaces.
For a rifle that's going to be used primarily outdoors like a car gun or camping rifle I take a whole other approach, I do not want it suppressed.
I remember a interview on the 1986 Miami FBI shootout, where the one FBI Agent said that the noise of the Mini-14 being fired in his direction was "demoralizing", for some reason that quote has stuck with me and makes a lot of sense.
Indoors the suppressor helps me more than it hurts, outdoors I think the concussion might be an advantage.
