RabidNinja64 Posted March 21, 2015 Posted March 21, 2015 Just a quick post, anyone know any decent upgrades for the 3PX4? considering this "HK/WE" model is essentially TM compatible, im hoping theres a trustworthy way to increase the FPS, such as changing the barrel/spring/nozzle/etc that has been found firsthand? Links appreciated.
