This is an excerpt of my mod pack with just the silenced weapons as requested by TORCHish. There is no gating of these weapons behind any recipes, just the recipes and items themselves.
To use, copy the items into the bottom of your items.xml file and change the IDs to be in consecutive number order from the last ID in your file. Copy the recipes to your recipes.xml file at the bottom.
Restart 7 Days to Die and enjoy the silence
