Product Description

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.
