The Yankee Hill Machine Complete AR-15 Lower Receiver (part no. 128) is designed and machined entirely in-house from 7075-T6 aircraft-grade forged aluminum, then finished with a hardcoat anodized matte black coating to military specification. YHM ships it fully assembled with a complete lower parts kit, an adjustable 6-position commercial carbine stock, and a standard A2 black pistol grip already installed, so builders only need to pull the takedown pins, drop in an upper, and start loading magazines. Oversized magazine well chamfers make reloads easier, and the receiver accepts all generations of PMAGs along with standard mil-spec upper receivers.
