The Umbra Ferrox bolter variant was mass-produced by Chapter Techmarines in order to ensure a continuous supply of arms and munitions during the dark days of the Horus Heresy. The Ferrox-pattern weapon exchanges the sickle clip for a box magazine, allowing for a greater ammunition capacity. The weapon features an inbuilt long-range gunsight, incorporating additional Target Reciprocator Systems that mesh with the Autosenses of power armour.
These 10 detailed weapons and optional combat blades are perfect for converting Sternguard Veteran Squads, their larger magazines representing the capacity to choose between the various special ammunition types detailed in Codex: Space Marines.
