Alright, this gun worked great with just one shot loading, but I wanted it to have a clip, so it could be a real longshot once more. I thought it would be easy, turns out I was wrong. The first thing I did was to make a cover for the top of bolt sled, since it sticks out and darts that drop in from behind it would get jammed.
Here is the cover:

It looks really cool when it goes into the gun shell:

Then I put a clip on top, but even then I could see one huge problem:

Here it is with the cheat:

Here is the problem:

Since there is such a huge gap in between the clip and the breech, several darts will fall in, ometimes even flipping in the long fall.

This is rather problematic when you push the bolt forward.

So, I've been racking my brains all morning trying to come up with something that will solve this problem. None of my ideas went anywhere, so I'm asking all you intelligent people to see if you have any. Feedback is greatly appreciated.
