Yankee Hill Machine Rifle Lowers for Sale

Yankee Hill Machine Co., Inc. of the United States is a longtime AR-15 player in Rifle Lowers, with the YHM-15 line in production since at least 2013 and later expanded to include a billet lower as part of a matched receiver set. Their Rifle Lowers are machined 100% in-house from 7075-T6 aluminum with hard-coat anodizing and oversized magazine-well chamfers, while the billet variant adds an integral enlarged trigger guard and a receiver-tension screw, maintaining broad Mil-Spec parts compatibility and acceptance of all PMAG generations.
