YHM complete lower upper match
Reviewed on May 4, 2026Verified with Build

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.

YHM complete lower assembled
Reviewed on May 1, 2026Verified with Build

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.

YHM complete lower no pins
Reviewed on April 29, 2026Verified with Build

YHM complete lower with M4 stock is mostly ready to mate to an upper. Wish takedown pins were included since I had to source separately. Stock locks tight on the included tube. Mil spec trigger is functional baseline.
