M249 MK48 Style (200rnd Real Steel) Magazine + Insert

M249 / MK46 Style 200-Round Magazine Insert

Holds Approximately 5,000 Rounds

A compact, high-output feeder built around Bull Craft’s proven Cattle Drive™ Springless Clutch Drive Feed System. This 200-round insert delivers the same jam-free, motor-driven reliability found in our flagship drum magazines—scaled down into a rugged, drop-in package for M249 and MK48-style magazine shells.

Engineered for consistent feeding under sustained fire, the Cattle Drive™ system eliminates traditional springs in favor of self-clearing clutch torque, reducing drag, wear, and feed failures. A high-torque motor with external speed control allows precise tuning from low cyclic rates up to 40+ rounds per second, giving you full control over your setup.

Designed to run on 7.4v or 11.1v LiPo, this insert installs cleanly with no modification required and is constructed from battle-grade SLS-printed Nylon PA12 for impact resistance and long-term durability. Both the insert and the outer magazine shell are designed, printed, and assembled in the USA, then tested in-house to ensure real-world reliability.

______________________________________________________________________________________

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.

• Weight: 1.07 lb empty / 3.1 lb loaded with 0.25g BBs
• Compatibility: PolarStar, Wolverine (TCU required)

⚠️ 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

⚠️ 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.
