i didn't up grade till i gamed it at least once or twice then after that it spent most of its time in parts.the parts that came with are clear plastic crap but other than that every thing els looked alright.two months it is still not finished its shooting at 355 with .20 gram BBS and to top it off metal receiver and wood kit the last thing to go on it is the metal front end so after all that a kraken is a good platform to build upon i would not game it unless all the crap parts are replaced with better ones. i will post pics when it is done later next week
