What gun and spring were you using out of curiosity?

I forget the url link, but I think on the same page someone mentioned a barrel that was drilled in a spiral fashion along the length of the barrel (similar to real silencer designs) to "silence" the gun. Just throwing my find out there
I'll look for the link soon.
