Does anyone know where i can purchase or find a mod for the Gauss Rifle?

The fallout wiki and spelling correctly are you friends.

According to the Fallout NV wiki (link below), there are no mods available for the Gauss Rifle.

Thanks for that info, but as ive come to know, The wiki can be wrong. So i was just curious if anyone had found one.

It's easily checked in the GECK. There are no weapon mods for the Gauss rifle.
