Laser

I'm not sure if anyone has seen it, but in some mods you can get a laser. I'm sure we've all seen the laser you can put on your guns and such, usually comes with wall-hacks. Well in some svers, like the old 4THID zombie modded server, or the current zombie server hosted by synx, when you got last human you'd get a pp2000 silenced with explosive bullets. This is made more awesome by the fact that whenever you shoot it, a laser shoots out of the barrel, everyone sees this laser as it's part of the mod. If you've never seen it you should, I only know of one server that you can see it from. If you know what I'm talking about, can you make a mod that does this to all of your weapons? Something that will make it so that when I'm in game my gun shoots a laser?

ive seen it too. but i don't think you can get it in the textures section
