Echo1 P90 I am trying to make my gun awesome, but need help. I bought an echo1 p90 because I personally love the look of that gun body. I have also bought an angel customs stock extension, the matrix terminator kit, an AIM 4X32 illuminated scope with fiber optic sights, a mad bull stubby forward grip, an AIM AR series bipod, and an AIM 363mm 6.03 inner barrel. That stuff I didn't need help with getting, but now that i am done with the externals, I want to make it shoot smoothly most of all, and about 1100 to 1200rounds per minute. It came with a 9.6V battery and I think it came with a M120 spring... But I have not done anything to its gearbox, so I could be wrong. It would be an amazing help if someone could help point me in the right direction with specifications and specifics about what items I am going to need to buy. I would like to spend under $300, but i am willing to go to $400 if needed.
