⚠️ 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
