YHM STRIPPED LOWER 9MM BLK

Yankee Hill Machine Co Stripped Lower Receiver, Semi-automatic, 9MM, Matte Black, Made from 7075-T6 Aluminum, Accepts Colt Style 9MM Magazines YHM-135

This semi-auto lower receiver lets you build a dedicated 9mm AR. The magazine well is machined to accept Colt style 9mm magazines and this eliminates the need for a separate conversion block and the reliability problems that can result from converting a standard .223/5.56mm lower with add-on parts.
