Limited to the supplied IGN table, which lists five Service Weapon forms and their mission availability. The source is for Control, with no Ultimate Edition, DLC, or NG+ distinctions stated; no variants beyond the sampled rows are inferred.
Counts describe the imported source tables. They do not establish complete coverage of every patch, DLC or upgrade variant. Multiple values remain labeled as listed values when the source does not identify their upgrade levels.
The supplied guides say not all forms are craftable immediately. IGN also advises waiting to upgrade a specific form until more forms are available or you are confident in that form.
Mod availability can depend on unlocked forms or abilities
The Mods page says ordinary acquired mods are limited to currently available forms and abilities, with Board Countermeasure rewards noted as an exception. It also describes only one mod slot per form in its basic variant, with further slots from upgrades.
Higher rarity does not guarantee a stronger effect
The Mods page says effect ranges can overlap between rarities, so a lower-rarity mod of the same kind can sometimes have a higher stat improvement than a higher-rarity one.
A focused reference to Service Weapon forms and selected named Weapon and Personal Mods. It covers form behavior, several mod effects, and cited availability or slot rules. It does not attempt complete coverage of abilities, all equipment, exact upgrade costs, or comparative effectiveness.
Edition and mechanic limits
The mods page combines base-game, expansion, Expedition, and platform-specific entries. Expansion and platform context is included only where the passage states it; not every listed mod is established here as available in every edition or platform.
The IGN page predates the Ultimate Edition and differs from the Ultimate Edition Help Center on some form availability mission labels. No disputed unlock label is used as a definitive progression fact.
Ability upgrade branches and exact ability upgrade costs are not detailed in these passages. The selected ability-related records describe named Personal Mods only.
