My son got an Outkast RTP kit for his b-day, and other than a barrel (J&J Ceramic 12" Spyder thread) and hopper (Tacamo Arc dual feed gravity hopper) we're not sure what else will fit it. He wants a buttstoc, (He mostly plays woodsball) but JT doesn't offer their own. I know it's a top cocking stacked-tube blowback Spyder clone. Would a stock that fits any Spyder top cockers fit his gun? How bout bolts, grips, etc? I know that this is a "starter" gun, and many ppl will try to talk us out of dumping $$ into this gun, but my son loves the idea of a "sleeper". He wants ppl to see his "Walmart special" gun and not take him seriously. That way, when he lights up the "hot shots" with their high dollar equipment, it's more humilliating. (LOL) ANYway, any advide would be a big help.
