@Bufger: Don't know about modding the Phenom magwell for a different mag - the magwell is cast as part of the recievers, rather than the handy plastic slide-in well on the X7 Classic (as some are calling it now ). I would say be 100% sure that's what you want to do before you start chopping metal out of your shiny new Phenom! I'm sure other folks on here will chime in with some tips on modding the mag - I'm saving for a Phenom just now too, and I hate the look of the ikkle 9mm mag! One option, if you don't mind shelling out a bit and shipping stuff from the States would be to look up ScenarioArms on Google. Run by a guy Dhallak who's a regular on the A5og and X7og forums, and I've spotted a few of his products so far in the galleries on here, so others will be able to advise you on ease of getting stuff from him. He does replacement mags and magwells that fit over the existing well, meaning (as far as I'm aware) no permanent modification required to the recievers. That would be one way for an M4-esque mag. Keen to see where you go with this, as it will inform my mods when I eventually get mine!
