I am new to the forum. I don't yet own an AR I am more of a FN FAL guy. My wife is getting interested in going shooting with me but she is barely 5' tall. I would like to get a postban M4 style for her. I really dont care if the stock is A2 style or folding style it just needs to be shorter. Is it legal to put a folding stock on and have it permanently welded, or fixed to the shorter position? Does someone make an A2 style 2 inches shorter? Or can the permanently fixed folding look alike be permanently shortened? please don't tell me to "just get a pre-ban".
