The short answer

At least four — a pre-release trophy requires it. Whether four is the maximum has not been published.

In full

What that means when you are planning

Every weapon has a set number of Modification Slots, and EA say that number can be increased over the course of the campaign. So the answer is not fixed: it starts lower and grows.

The four comes from an achievement that asks the player to equip four Weapon Mods to a weapon. That proves four fit at once. It is worth being precise about what it does not prove — nothing states four is the ceiling, and a trophy asking for four would make just as much sense in a game whose ceiling is six.

For planning, the useful reading is that four is a floor you can count on reaching. Whether a fifth slot is worth chasing is a question nobody can answer until the retail game shows the upgrade path.

Open questions

Points the shipped game has not yet answered for us, or that need a controlled comparison to state as fact — recorded rather than guessed at.

How many Modification Slots each weapon type starts with.
What raises the slot count, and how far it goes.
Whether the maximum is four or higher.

What do Weapon Mods do in Zero Company?: They slot into a weapon, change its stats, and can add effects of their own — one applies stacking Burning on every hit.
How many weapon types does Zero Company have?: Four: Longarm, Repeater, Rifle and Pistol. There is no fifth.
