Query: This gun exploded

I got one of these because it was only a penny. I used it several times with only a slight crack that I later cemented. Later I used it again, and, while cocking it back, the whole top piece just splintered into many pieces. The gun is fun for about the first few tries then it's prone to jamming up. Even though it was only a penny, it was $4.99 shipping. I'm better off getting one for about a dollar at a flea market. I'm not very satisfied, but I'm not spending 40 cents to get my 1 penny back.
