I purchased my M4 A1-X-MAX CTW 6 months ago from AIRSOFT CENTER in Greece,I have used it at about 20 games since then and I only had a burned fuse the first time I used it but I guess I wasn't using the right battery.Since then everything is ok.I found this forum's discussions very interesting and helpfull,and this is the reason I decided to register.
