Well everyone said this to me so make a intro post. This is how go to the beginner section and as a subtopic you should see introduction. That is the wrong kit and with all kits like that they are usually crap. Here is a link to the gun that the upgrade kit fits in. http://images.hobbytron.com/LP-SOFT-M324SR-A-lg.jpg . The upgrade kits if your looking for cheapy but maybe sucky go with the Evike rebrand. I think they are decent not the best.
