Yankee Hill Machine complete lower with M4 stock lines up perfectly with my YHM upper. Anodize matches between receivers. Stock locks tight on the included tube. Standard mil-spec dimensions for all the lower parts kit components.
Yankee Hill Machine complete lower with M4 stock arrives ready to mate to an upper. Anodize matches their other parts. Mil spec trigger is functional but replaceable. Stock locks tight on the included tube. Good base for a complete build.
