M249 / MK46 Style 200-Round Magazine Insert
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 MK46-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.

⚠️ 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
Don’t trust your loadout to inferior clones. Choose the original. Choose Bull Craft.
