Gun customization is a feature that appears in Metal Gear Solid 4: Guns of the Patriots and Metal Gear Solid V: The Phantom Pain. In the latter, once unlocked by finishing the 3 legendary gun smith side missions, unlocked after mission 13, the player can modify guns in their ACC. The more guns the player has, the more parts they can use to customize.
