Just curious to why your taking apart your bushy? I mean its good to get to know your marker and all, but you have to be really careful when you disasemble the marker. Keep your trigger frame intact as well( don't take out the microswitch ect.), because if your not upgrading anything, then there isn't any reason to take it apart. Same for the rest of the gun, not a whole lot really needs done with the internals of a bushy, just clean/oil your reg every once in a while and make sure you clean your bolt after every use.
I'm just saying, if you take your marker apart, pay attention to how you take it apart, then just put it back together that way. Never use paintball oil for lube, use slick honey or something like that. Also be careful around the barbs, don't pull the hose off of them, or you'll most likely need a new hose for that(first time i took off my hose, i messed up my barb and the hose, so just be very careful). Be sure not to pull to hard on the wiring harness either, or then you'll need to solder that back on. Basically all i'm saying is just be very careful, read up before you just go taking everything apart, because your bound to break something

. Have fun
