Improved Custom Guns Mod is a modification for Tom Clancy’s Rainbow Six 3: Raven Shield, created by .Twi.
Description (in author’s own words):
This mod allows you to use custom guns and gadgets on your server. It's a better, greatly improved version of my old mod that did the same thing. This new version fixes tons of bugs and is basically 100x better.
