Are Quad Rails Dead?
This video evaluates the current relevance of quad rail systems on AR-15 platforms, specifically testing a Daniel Defense DDM4 V9. While M-LOK is still preferred, the quad rail on the DDM4 V9 proved to be a viable option, with surprisingly manageable weight and effective heat dissipation when using rail covers. The rifle was found to be sturdy and well-balanced during manipulation and target transitions.
