Overview
The Yankee Hill Machine YHM-300A is a precision-machined, mil-spec scope ring set purpose-built for AR-15 platform rifles. Engineered by one of the most respected names in American AR-15 manufacturing, the YHM-300A positions your 30mm scope tube at the correct AR-tall height, placing the centerline of the optic at approximately 1.4 inches above the top of the receiver, perfectly aligning your scope with the iron sight co-witness height of a standard flat-top AR-15.
These rings are sold as a matched pair and are ready to mount directly to any standard Picatinny rail with no modifications or adapters required.
