Hmm. Must be a Spyder thing. I had one of these guys a long time ago.
It was the very first real paintball gun I ever had. I was a bit careless with it, and let it get abused and trashed. For whatever reason, I felt really bad about it falling apart, and hunted one down. Found the same gun on ebay, won it for $45 bucks. And it's in really nice shape, to boot.
I think I felt bad because it was a gift from my dad, for my 15th birthday. It's silly, but I smile every time I look at it.
