# Weapon Mods Weapon mods attach to **four slot types**: muzzle, scope, underbarrel, and magazine. Each weapon has a fixed set of available slots. Mods that are enabled modify weapon stats multiplicatively (scalar) or additively (offset). ## Mod Slots | Slot | Description | | :--- | :--- | | Muzzle | Silencers, muzzle brake, muzzle boost | | Scope | Sights and scopes (holosight, 8x, variable zoom) | | Underbarrel | Flashlight, laser sight, targeting attachment | | Magazine | Extended magazine, burst module | ## Special Properties | Mod | Slot | Properties | | :--- | :--- | :--- | | ![8x Zoom Scope][icon-weaponmodsmallscope] [8x Zoom Scope][item-weaponmodsmallscope] | Scope | 4x zoom, Must be toggled on | | ![Burst Module][icon-weaponmodburstmodule] [Burst Module][item-weaponmodburstmodule] | Magazine | 3-round burst, Must be toggled on | | ![Extended Magazine][icon-weaponmodextendedmags] [Extended Magazine][item-weaponmodextendedmags] | Magazine | - | | ![Gas Compression Overdrive][icon-weaponmodgascompressionovedrive] [Gas Compression Overdrive][item-weaponmodgascompressionovedrive] | Muzzle | - | | ![Holosight][icon-weaponmodholosight] [Holosight][item-weaponmodholosight] | Scope | - | | ![Military Silencer][icon-weaponmodsilencer] [Military Silencer][item-weaponmodsilencer] | Muzzle | Silenced | | ![Muzzle Boost][icon-weaponmodmuzzleboost] [Muzzle Boost][item-weaponmodmuzzleboost] | Muzzle | Faster fire rate | | ![Muzzle Brake][icon-weaponmodmuzzlebrake] [Muzzle Brake][item-weaponmodmuzzlebrake] | Muzzle | Reduces muzzle climb | | ![Oil Filter Silencer][icon-weaponmodoilfiltersilencer] [Oil Filter Silencer][item-weaponmodoilfiltersilencer] | Muzzle | Silenced | | ![Simple Handmade Sight][icon-weaponmodsimplesight] [Simple Handmade Sight][item-weaponmodsimplesight] | Scope | - | | ![Soda Can Silencer][icon-weaponmodsodacansilencer] [Soda Can Silencer][item-weaponmodsodacansilencer] | Muzzle | Silenced | | ![Targeting Attachment][icon-weaponmodtargetingattachment] [Targeting Attachment][item-weaponmodtargetingattachment] | Underbarrel | Allows target pinging | | ![Variable Zoom Scope][icon-weaponmod8xscope] [Variable Zoom Scope][item-weaponmod8xscope] | Scope | 8x zoom, Must be toggled on | | ![Weapon flashlight][icon-weaponmodflashlight] [Weapon flashlight][item-weaponmodflashlight] | Underbarrel | Light source | | ![Weapon Lasersight][icon-weaponmodlasersight] [Weapon Lasersight][item-weaponmodlasersight] | Underbarrel | Light source, Must be toggled on | ## Effect Matrix Only **active** effects are shown.
