The “Magazine Extender Mod” is, as the name suggests, a weapon mod that increases the ammo capacity of your gun’s magazine. Once you read this Schematic, you’ll be able to craft this mod yourself at the appropriate workbench and similar stations. The schematic itself is single-use, and once read it permanently unlocks the recipe—the common behavior shared by this type of schematic item.
Why It’s Worth It
A larger magazine capacity means more rounds you can fire on a single reload. It reduces those situations where you’re “one shot short and forced to reload” during drawn-out fights like the Blood Moon or when taking on a horde. It pairs well with assault rifles and SMGs that win through volume of fire, serving as an unsung hero that boosts your DPS from the raw ammo-count side.
How to Get It and When to Use It
Schematics are a category you’ll often find as loot while exploring or purchase from a trader. Even if you draw a duplicate, there are situations where crafting it yourself keeps material costs lower than buying the part, so if you’re the crafting type it’s worth unlocking early.
For the gun you attach it to, we recommend prioritizing your main weapon with a busy reload tempo. Mod slots are limited, so be aware that it competes for a slot with damage or scope mods, and work it into your loadout to match your own fighting style.
*The exact amount of capacity increase and the slot specifications can change between versions, so give it a final check with the in-game tooltip.
