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. ________________________________________________________________________________________________ ⚠️ Don’t Be Fooled by Knockoffs The Cattle Drive™ Springless Clutch Drive Feeding System is often imitated—but never duplicated.
