PKM High-Capacity Magazine Systems

Micro 5000+ Magazine or 5600rd Box Magazine Insert

Compact power or maximum sustain. Same relentless feed.

The Bull Craft PKM High-Capacity Magazine Systems are built around our proven Cattle Drive™ Springless Feed System, delivering smooth, uninterrupted feeding without jams, drag, or warping. Whether you want a standalone compact magazine body or a high-capacity box magazine insert, both options are engineered for real-world reliability and sustained fire.

Designed, printed, and assembled in-house using SLS-fused Nylon PA12, these systems are built to survive hard use while keeping feeding consistent when it matters most.

⚠️ Important HPA Compatibility Notice — READ BEFORE PURCHASE

All Bull Craft drum magazines and inserts require a Trigger Control Unit (TCU) when paired with HPA platforms such as PolarStar or Wolverine.

• Standard FCUs do not provide sufficient power for motor-driven feeding
• With a TCU installed, feeding activates automatically on trigger pull
• Already running an Airsoft Junkiez TCU? You’re good to go — full compatibility confirmed

⚠️ Don’t Be Fooled by Knockoffs

The Cattle Drive™ Springless Clutch Drive Feeding System is often imitated—but never duplicated.

• Designed, refined, and proven in-house
• Built with premium SLS Nylon PA12 and robust motor systems
• Backed by real-world testing, not marketing fluff
