Jaeger Precision shows the installation of a TAPP Airsoft Hybrid HPA Kit onto a GHK G5 rifle. He starts with disassembling the original G5 lower and then installing the new hybrid lower and its components. Please note that the key steps include modifying the grip for the HPA airline, assembling the trigger box, and reassembling the selector switch and body pins. There were challenges during the assembly but he was satisfied with the final result, noting the strong blowback action and consistent output. He also tested magazine compatibility, finding that ASG Scorpion Evo magazines worked, but PTS Evo magazines did not.
