SRU Airsoft AR Bullpup Kit
This guide details the installation of the SRU AR Bullpup Kit onto a Classic Army M4 Airsoft AEG. The process involves disassembling the M4, integrating its core components (gearbox, motor, receiver extension) into the 3D-printed bullpup chassis, and reassembling the unit. Key considerations include the trigger bar connection, battery placement, and potential modifications for hop-up access. The kit transforms a standard AR platform into a compact, futuristic bullpup configuration.
