So I am bored and have a Psycho Ballistics Silver Bullet sitting around that my brother got for free and has no interest in tinkering with. I have been told it is a Spyder clone. I would assume this means it could take the same upgrades that most Spyders can?? Looking at the feedneck, it is the same as a spyder, but my main interest is getting a higher ROF out of it.  From what I read it tops out at around 10bps, but would be interested in bumping it up to 15-20 if possible. Does anyone know if an upgrade board for a Spyder should/would fit it? If so, are there any recommendations? I have thought about doing some grinding/milling on it and maybe getting it stripped and reannoed as well. If it is Spyder compatible, what other things should I look at? I don't want to dump a ton of money into it, but if I can get a reliable shooter for a $100 or so, would be interesting since I have nothing into it yet.
