Ok. Here's the deal. I've got about $250 to work with. I can go up to probably $300. Max $350. Anyway. I've been airsofting for a couple years and want a new AEG. I've had a basic m4 for a while. I'm looking for something that not everybody else has. Something unique. I would like it to be easily upgradable internally. Something a little bit shorter than most m4's (I'm planning on adding a mock suppressor/silencer). And have an fps of about 370-400 out of the box. Also, a retractble/folding stock. Preferably full metal. I've looked around and the closest I have come to those specs and my price range is the ICS SIG 552 commando. Any thoughts on that? I wanted the Echo 1 XCR. But, as most of you can tell, that's out of my price range. Anyway, thanks for any help I recieve!
