Harrington & Richardson

Overview

The Harrington & Richardson BLEM "Slickside" Upper Receiver is a stripped upper designed for the AR-15 platform, specifically built to accommodate 5.56 NATO caliber. Its slick side configuration means it lacks forward-assist features, providing a cleaner aesthetic and potentially lighter build. This upper receiver is commonly found in builds utilizing a carbine gas system, making it a solid choice for those looking to streamline their setup.
