sheesh he's just asking what we recommend what to get with it.
for a beginner, get a spare hicap mag and a spare battery. I like to leave a bottle of BBs on the field when playing for reloads (just dont cry if its stolen or borrowed from).
From what I gather, it's not really worth it upgrading the internals on the combat machine.. but a vertical grip is always nice, so is a red dot (especially if you play indoors).
DIY goggles, lower face mesh. BOOTS. cheap military trousers and jacket. maybe a cheap vest, but pockets will do for beginners. gloves can be nice as well.
dont bother with a radio unless you played a few games and feel you need it, most people play without.
oh, almost forgot, something that covers your ears can be real sweet, those shots can hurt!! especially on cold days!
