Hello hopup this is a CAA licensed full metal m4 carbine it is listed on evike for $230 new it is not new I was given it by a friend a while ago after he had an issue with it the only problem is that It needs a new trigger contact which you can find on evike for $4 you can have your local fields tech install it or you can do it yourself just look up a video it is quite simple if you just follow the video, the mag seen in the picture is a 190 round mid capacity magazine that will be included with it this gun runs best on a 9.6v nimh battery. I would much rather cash but I will take a look at tr.sde just feel free to send me pictures of the item you want to tr.ade and a description please feel free to message me with any questions.
