So I just got an almost new in box AUG A3M1 in trade for one of my ARs, and it just so happens to be a short rail variant...my least favorite optioned model. Because I never planned on getting any of the M1 models, I don't know as much about them as I prefer the much longer railed A3SA models. Are there any longer rail options for the M1 models? If not, can I swap the rail off of a long rail M1 onto the short rail model I have? Hell, are the rails even removable on the M1 models? Hell, I'll even trade it for someone's long rail model, or A3SA model if it saves time and money.
