Airsoft Mechanic GR has showcased another custom work, a VFC M4, built to operate at 1.6J and 30 RPS. The customizations include a 30K boost motor, 13:1 gears with a short stroke of 3, full Lonex compression, and an advanced Gate Titan. It also features a Prowin on a Prometheus R-hopped barrel among other enhancements. To top it all off, it sports a full dusty paint job, adding to its unique appeal.
