The Yankee Hill Machine YHM-125 stripped billet lower receiver gives you a foundation for a custom AR-15 build that stands apart from the cookie-cutter crowd. Machined entirely in-house from 7075-T6 aluminum, this billet lower combines precision engineering with a distinctive design that refuses to blend in. If you're building a rifle that reflects your own vision rather than copying the same profile as every other AR on the rack, this is where to start.
What makes the YHM-125 practical for builders is attention to the details that matter during assembly and use. The oversized magazine well chamfers make feeding rounds smoother and magazine changes faster—a small feature that pays dividends at the range or in the field. The integrated oversized trigger guard is machined as part of the receiver itself, so you're not hunting for a separate component. It accepts standard mil-spec upper receivers without modification, and the magazine compatibility covers all generations of PMAG ammunition carriers, giving you flexibility in your setup.
Durability is built in from the material up. The hardcoat anodized matte black finish meets or exceeds military specifications, meaning this lower is ready to handle the wear of actual use. Whether you're assembling a precision rifle, a hunting build, or something for the range, the YHM-125 gives you a solid platform that looks and functions as good as it performs.
| Material | 7075-T6 Aluminum (Billet) |
| Finish | Hardcoat Anodized Matte Black (Military Specification or Better) |

Yes. The YHM-125 accepts all mil-spec upper receivers, so it integrates with any standard AR-15 upper you already own or plan to source.
The YHM-125 accepts all generations of PMAG magazines. The oversized magazine well chamfers make insertion and removal smooth and reliable.
This is a stripped receiver only. You'll need to supply your own trigger, fire control group (hammer, sear, disconnector), safety selector, and stock or buffer tube assembly to complete the lower.
Yes. The trigger guard is integrated and machined as part of the receiver itself, so you don't need to source or install a separate component.
