Please read full description. This is an original Jing Gong Navy M5. These are super hard to find and on top of that, this is the full metal version from body to magazine. Most of them are discontinued and the ones you can find are shipped from Japan and aren’t full metal(I found that out the hard way). The rail for this one is not included as it is broken, but it can easily and cheaply be replaced with most of your favorite MP5 rails. The original scope mount is included. I can also throw in other mags. It’s only been fielded once or twice so still shoots like new, I just never used it after the rail broke. New inner barrel and motor, can provide shooting video upon request but please only if you are a serious buying. Not really looking for trades unless you have an upgraded Echo 1 Gat. Thanks for looking!
