I've been thinking about selling my Pre-Ban Aug A1. I have a USR and an A3 as well and I prefer the A3. Is there any particulary value in the pre-ban aug or the USR? I was trying to figure out whether there is a legal process for converting the A1 to full-auto or if there's some reason why I would miss it in the future. Otherwise, I'd just as soon sell the A1 and buy another A3. Probably do the same with the USR.
