Magazine for Gamo Swarm Maxxim .22

OK guys this is my first real project. So its not pretty by any means. I havent done to much in fusion and this is the longest. But I learned a lot. I got it pretty close and almost there. But there is still a lot to make this model look good and working. This is about as far as I was able to get. If someone can help out and make it better please feel free to and contact me with the update.
