I recently took my gun apart to spray it and stupidly I didn't take note on how to put it back together and where parts go. Is there a assembly video for the full gun, I didn't take the gearbox apart so that is still alright. But the main parts i dont know how to put back together are the trigger, fire selector switch that and the whole trigger switch assembly. any help would be massively appreciated even if its not a video just word advise word be amazing
