The HF-601 represents a collaboration between Hodge Defense Systems and Forward Controls Design, combining precision engineering with field-tested design expertise. Machined from 17-4 stainless steel on Swiss machines to exacting standards and tight tolerances, these takedown and pivot pins receive a black nitride finish. The HF-601 pins measure 0.040″ longer than standard TDP takedown and pivot pins, delivering enhanced ergonomics for quicker field disassembly.
The HF-601 draws inspiration from classic AR lineage, with design cues faithful to the Colt 601. The takedown pin features dimples on both sides, the pivot pin includes dimples on the left side, and the takedown pin tip carries a slight ring on its left side. These pins maintain standard TDP diameter tolerances of 0.2485 +0.000/-0.005, ensuring reliable fit and function with any AR-15 lower receiver. the HF-601 offers the durability and handling improvements that serious shooters demand.
