Rap4(rap4.com) makes the accesories for the automag. The butt stock is called the Viewloader Carbine Buttstock. It is compatable with all markers. As for the front....pick a barrel length of your choice then go to Tapco.com and order a M-14 carbine hand guard that will fit a 1 inch barrel. I bought one from them for 5 bucks to fit on a J&J ceramic barrel.It is ALOT cheaper to get the front guards from a real gun site then it is to buy form the paintball web sites.
The clip uuummmmm.....not sure may take a little searching to find.
