no need for upgrades, the only upgrade i did for my FAL was a better nozzle and spring guide. As for the M4 all you need is a stiffer spring to reach pass the 320fps but why??? at stock version my CQB was at par with some of the modified AEG. King Arms are made ready to run picture them as a HK version of Tokyo Marui
