Lego AK-47 Thing

I failed making the HK-416 so I decided to retry and use the same mechanism but instead, I will make an AK-47. I hope I will succeed. I am also making a brickfilm, The Fifth Target. It is going to take a long time. I just wrote the storyline.

I took a look at this video and tried to make something that looked similar. Actually it might not even be an AK-47, it might be a different gun.
