Understand Primed Ammo Stock
Useful when…
- Increase a shotgun’s magazine capacity.
- Reduce how often a reload interrupts firing, depending on the weapon and build.
Effect and application
Primed Ammo Stock is a Legendary standard-slot shotgun mod with Naramon polarity. It adds +10% Magazine Capacity at rank 0, +60% at rank 5, and +110% at rank 10. The effect concerns magazine capacity; it does not list a fire-rate or reload-speed change.
Ranks and alternatives
The listed rank 5-to-6 fusion step costs 1,280 Endo and 61,824 Credits; rank 9-to-10 costs 20,480 Endo and 989,184 Credits. Standard Ammo Stock lists +60% magazine capacity at rank 5, while Flawed Ammo Stock lists +20% at rank 3. Primed Ammo Stock explicitly excludes both Ammo Stock and Flawed Ammo Stock, so treat them as alternatives.
Different shotgun effect
Accelerated Blast lists +60% Fire Rate and +60% Puncture. Those stats do not increase magazine capacity; they address different weapon properties and compete for a standard mod slot.
Limitations and tradeoffs
- More magazine capacity can mean fewer reload interruptions, while the Primed mod’s final ranks have high listed costs.
- Capacity competes with other standard-slot shotgun mods.
Common mistakes to avoid
- Attempting to equip Primed Ammo Stock with Ammo Stock or Flawed Ammo Stock despite the listed exclusions.
- Expecting magazine capacity to increase fire rate or reload speed.
