Also, if a mod is needed to fix it, how do you know it's even a bug? I mean this is CoD. They often reuse assets. It's completely likely the weapons use the same overlay on purpose. And given the game files themselves so no evidence on cut reticles (which we would cover if they did) furthers this overlay is done on purpose. Ergo, this does not fix a bug, it merely mods an overlay texture to a different one. Therefore this blog is nothing more than a mod plug.
