My AR pistol has an 11.5" bbl. No problem with functioning. It has a carbine length buffer tube and can be held to the shoulder to fire. I can easily hit steel at 100 meters with it. SBRs are not allowed in my state so this is as close as I can come to one. Personally I wouldn't go shorter than a 10" bbl.
