I own my KAC PDW for almost 1 Year (open bolt). I'm not a skirmischer but I go every month to our families landhouse in the forest. And... It is in the forest that we have fun with our airsofts together with friends and family: just fun. Afterwards, the guns are not used for a month, not mentained, not lubricated, nor.... We shot minimum 250 mag's with the WE PDW without any single problem (even in the rain) so... What do you just do with your guns to have all these problems?
