A simple mod to make all rifles and pistols silenced. This mod edits Inventory files in Data3 to make the guns sound suppressed, and also edits the Aggression file in Data3 to make the A.I. not hear the changed weapons too. Together these edits make the weapons function and sound suppressed. No thanks at all to Rupert the "Gunsmith".

There are separate downloadable files for "rifles and pistols", "Marksman only", and a merged file for "both" versions.
