T2 MK5 assault rifle - imfdb :. guns in movies :. movie guns :. the internet movie firearms database Hey dudes, So I have a SAP AAA rifle, the pistol version without a stock. I am wondering if there was any way I could attach a folding stock to this bad buy, considering how rare it is and how I can't find any factory parts on the web. Is there any way to get an adapter or something that would allow me to attach AR-15 stocks? Can anybody help me out? Thanks.
