This custom HK416 Delta Custom FDE build by Prime Mech Airsoft demonstrates a high-performance transformation of the Tokyo Marui Next Gen Recoil Shock (NGRS) platform. The build integrates a Leviathan NGRS optical MOSFET for advanced programming and response, paired with a high-torque T238 28k brushless motor to ensure exceptional efficiency and a rapid rate of fire. Fine-tuned for consistency and power, the rifle delivers a formidable output of 1.6 Joules using 0.32g BBs, successfully merging the iconic aesthetics of the "Gucci" Delta Custom with modern, top-tier internals.
