I'm afraid that this gun is the worst out of your previous you are unable to remove the shell and it is too fragile you could also have expanded the magazine to eleven. Unlike myself you are an amateur.
P.S. 2nd gun was good but make so you don't have to drag shell out chamber automize that
terrible design bullets are too small and there are not enough magazines
i just downloaded cause i wanted to dissect the bullets
p.s ingenious bullet system ill use your design
