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.

All Bull Craft drum magazines and inserts require a Trigger Control Unit (TCU) when paired with HPA platforms such as PolarStar or Wolverine. Without a TCU, standard FCUs lack power for motor-driven feeding. This applies across our drum & insert lines — if it runs HPA, it needs a TCU. With a TCU installed, feeding activates automatically on trigger pull. Already own an Airsoft Junkiez TCU? You’re good to go—our system runs seamlessly with it.

⚠️ IMPORTANT – Connector Not Included

Your magazine or insert is supplied with approximately 6.5" of wire and no battery connector installed. This allows you to choose the connector that best fits your setup, whether that's JST, Deans (T-Plug), or another connector of your choice.

We're happy to solder on your preferred connector at no additional charge, but because every gun and battery location is different, we don't know what wire length your build requires. If we install a wire that's too long, you'll have excess wire inside your gun. If we install one that's too short, it may not reach your battery, requiring you to re-solder it anyway.

If you already know the wire length you need, simply leave us a note with your order. We'll gladly cut the wire to your requested length and solder on your preferred connector before shipping.

This approach ensures you receive the correct wire length for your specific build while giving you the flexibility to use the connector you prefer.
