Primed Ammo Chain

Primed Archgun ammunition capacity mod

Released Feb 17, 2026

Primed Ammo Chain raises an Archgun’s maximum ammunition capacity. Consider it when carrying more ammunition matters; it is a capacity increase, not a reload-speed or ammunition-efficiency effect.

Primed Ammo Chain GUIDE

Understand Primed Ammo Chain

Useful when…

  • Increase maximum ammunition for an Archgun.
  • Use when ammunition capacity is a priority and the standard slot is available.

Effect and compatibility

Primed Ammo Chain is a Legendary standard-slot Archgun mod with Naramon polarity. It increases Ammo Maximum by +15% at rank 0, +90% at rank 5, and +165% at rank 10. It explicitly lists Ammo Chain as incompatible, so the two variants are alternatives rather than stackable choices.

Rank tradeoff

The mod reaches rank 10. The listed rank 5-to-6 step costs 1,280 Endo and 61,824 Credits, while rank 9-to-10 costs 20,480 Endo and 989,184 Credits. The standard Ammo Chain comparison reaches +100% Ammo Maximum at rank 5, with the same listed polarity and a lower base drain; consider whether the additional capacity of the Primed option is worth the investment for your use.

Distinct ammunition-related effects

Archgun Ace instead triggers on a headshot kill, granting Fire/Charge Rate and Reload Speed for 9 seconds. That is a temporary handling effect, not added ammunition capacity. An Archgun Riven Mod is described as veiled and procedural, so its eventual effect cannot be specified from the supplied description.

Limitations and tradeoffs

  • The Primed version provides a larger listed capacity bonus but has a costly final rank step.
  • It does not itself list fire-rate, reload-speed, or ammo-efficiency effects.

Common mistakes to avoid

  • Trying to use Primed Ammo Chain together with the explicitly incompatible Ammo Chain.
  • Confusing maximum ammunition capacity with faster reloading or ammunition efficiency.
