VFC MP5SD6 V1 GBB SMG with 6 leak free magazines. When I got this it suffered from the normal VFC issues but I fitted a crusader feeding ramp and a couple of other aftermarket parts and it runs really well now.

The 6 magazines are leak free and work as they should. FPS is going to be gas and weather dependent. The inner barrel runs the full length of the SMG and finished at the end of the suppressor.

it's recommended to pull the bolt to the rear when changing magazine, just like the real thing, and the added bonus is you can HK slap the crap out of it since it's all steel.

It will come in a mystery box as I have no idea what happened to the original box.
