I'm extremely ignorant of Emags. I've owned a couple Automags, but never had the chance to try an Emag.
Just wanna know if they're PSP ready, because I would love to rock one in a tourney today.
I'm not 100% positive on whether an standard emag board flash is available that would be PSP 12.5 compatiable. However, if you're looking to shoot a mag with adjustability, you may want to look into picking up a home grown Egomag. Pretty neat little markers.
just an fyi Emags weigh over 3lbs, just the marker not including hopper and tank, this is the reason i shoot egomags instead of emag/xmag. But the answer to your question is yes you can make the emag xmag psp legal, im not sure if the stock board is but there are a couple aftermarket boards that deff are
