This mod is the standard material for all crafted baseball bats. Like most material swaps for the baseball bat, it is purely cosmetic and has no effect on weapon damage.
Weapon modifications will modify an existing weapon, and any modifications previously equipped on the weapon will be destroyed, not unequipped. Loose mods cannot be crafted. Despite being the standard material, this mod still has to be unlocked for crafting by means of weapon scrapping, each deconstructed baseball bat yields a low chance (15%) to unlock the mod for crafting.
