GPMG / FN MAG58 / 240B 50 Round Drum Magazine Airsoft Conversion

thingiverse

This is a cutting-edge auto winding system designed for a high-capacity 50 round drum magazine used in FN MAG58, 240 Bravo, GPMG firearms etc. The following essential components are required: -Insert - Requires the addition of spring tubing to the output tube that feeds into the MAG's hopup chamber. -Hop Up Chamber - Engineered exactly after the factory design, connects seamlessly with the spring tubing. -Feed Wheel - Threads securely into the top of a servo (recommended metal gear servo and high torque rated for 3S lipo). -Inner Sleeve - This slides effortlessly into the real steel box magazine and allows you to glue or adhere the insert directly to the inner sleeve, not the box mag, making this an authentic drop-in system. This innovative system has demonstrated exceptional performance at events and airsoft game days. I employed a DC PWM motor speed controller and ran the servo in series with the gearbox motor wiring so that when the motor in the gearbox spun, the box mag servo would turn and feed the replica. A speed controller is necessary to fine-tune the feed rate to your gearbox cycling rate. I successfully tuned it to misfire only every 15 shots or so.
