as far as i know mags can be done for everything but the g36's since the fake bullets make customs cranky... otherwise i believe we can bring extra mags down with us the m15/aug/ak/ca33/sarm41. still there is the chance that if we get a customs guy who is having a bad say it would not go well so it may be best to leave those at home, guess it comes down to the individual players.
all in all im happy to hear that this op is going down and i hope i will be amongst those who gets to make their way down for it.
