I can't remember what brand it was, but I cracked open a shell that used a small block of foam rubber instead of a spring under the tac rail tooth. Whenever I lose a spring, I use that trick. And sometimes it actually works better with foam rubber, so I replace the spring intentionally.

I'm 99% sure it wasn't a Hasbro blaster.
