Standard FCUs do NOT provide sufficient power for motor-driven feeding With a proper TCU installed, feeding activates automatically on trigger pull Airsoft Junkiez TCU is required. ________________________________________________________________________________________ ⚠️ Don’t Be Fooled by Knockoffs The Bull Craft Cattle Drive™ Springless Clutch Drive Feeding System is often imitated — never duplicated.
