this gun is awesome but does have a few PROBLEMS.....bbs sometimes get in the gears. Idk why it does this...in fact it's a new problem and you have to take the mag apart to get it out....other than that the gun never jams and cycles m4 mags well when held right....yes you have to hold it or rest it on your arm....this is expected with the gun....I knew that buying it.... The SAFETY is very loose and can be turned off or on by tilting the gun. The gun came like that but didn't affect me in game much. IT DOES COME WITH THE BIPOD but removed it because it got in the way. WARNING The gun has been collecting dust for a while and unsure if a new problem has appeared....not because of dust but problem I would discover if I played with it a couple more times like the battery. It did work well last time though. There are no upgrades and no flash hider. Be aware there could be problems that I haven't listed, it's very unlikely but I don't want to waste time and money on a item returned or just in case someone's trying to screw me over. If you do come across a problem just shoot me a text. Other than the problems and the legal jargon THIS GUN WILL THROW PLASTIC DOWN RANGE AS LONG AS YOU HAVE BBS AND YOUR BATTERY DOESNT DIE OR BURN OUT. If you want positive information about this gun find it on evike.
