Upgrading my tm ak47
 

Ok, what parts do i need to make it shoot harder, farther and more accurate. I mean i have an idea, like high pdi spring(how high? 210?), tight bore barrel, new gears i guess, a 9.6v battery to turn them, and what else? I see people talking about cylinders and bushings and all this but i dont know much about the internals on airsoft guns. Thanks in advance
