Hello all, I have a Raven EU Series G18. I am forever trying to get hold of some more gas mags. Patrol Base, Combat South, Ebay, Tango Down Airsoft, Most other usual haunts, none of which currently stock it. Seems to be a shortage. 1. Why is there a shortage? 2. Where can I purchase a couple of mags. The average RRP is £25, but ideally looking between £20-£30. P.s Apologies if this is the wrong place to pop a question but couldn't figure out where-else to ask, too many threads and chats...
