Mods are items that can be applied to weapons to receive various benefits. They are applied to weapons in the Weapons menu, which is found in the Unlocks tab.
Basics
The Mods page for the M82.
Mods can be obtained by finishing waves on any difficulty; the higher the difficulty, the higher the chance a mod will drop upon a wave completion. Similarly to Perks, every weapon has a specific number of mod slots that can be increased by either leveling the weapon up (1 slot every 3 levels, up to Level 12) through gameplay or by beating Wave 30 on Impossible mode. Unlike perks, once you install a mod, the only way to remove it and place it back in your inventory is to pay 49 ROBUX. You can replace an installed mod with another, but doing so will destroy the replaced mod.
When a mod is received, both the tier and the type of the mod are randomized, with higher tiers being rarer. Every mod has five tiers, with higher tiers providing stronger bonuses. All mods can both positively and negatively impact a weapon; negative effects are only seen starting with Tier 2 mods. Some mods can only be applied to specific types of weapons, and no mod can be applied to utility or consumable items. You can upgrade a mod to a tier higher if you own 4 of the same mod of the same tier. Recycling a mod gives 2 random mods of a tier lower.
It can be assumed that the formula for mod bonuses is PositiveStat*Tier & NegativeStat*(Tier-1).
