I have all three versions in my downloads here so I'll try to sort this confusion out.
The newest archive is named "Real_Recorded_Gunsounds_Mod_V3.rar", but the folder within the archive is named "Real Recorded Gunsounds Mod V2", this is probably the source of the confusion. The WEAPONS.ivaud file within is definitely different to the one from the V2 archive, though. Different filesize.
What really confuses me is, the video from the first post
is said to be of version 3, but the pistol, shotgun and AK sounds heard in the video match those from "Real_Recorded_Gunsounds_Mod_V2.rar". They're different again in V3.
Don't get me wrong, I'm not complaining about anything, just providing information.
Thanks again for the mod jclewis and friends. It's top work as usual. Sound effects can be very subjective but your mods (I use the one you made for Brothers in Arms: Road to Hill 30 too) always sound right to me. They're a massive improvement over the default sounds.
