Extended Medium Mag II Blueprint in ARC Raiders

The Extended Medium Mag II Blueprint is a blueprint that allows you to create the Extended Medium Mag II at a crafting station with a Gunsmith skill level of 2. This weapon attachment increases the ammo capacity of compatible weapons that use medium ammo, letting you fire more shots before needing to reload. You can purchase this blueprint from the vendor Shani for 100 coins, with a daily limit of two. It can also be found through scavenging.
