Overview
The Expo Arms AR-15 PCC Billet Slick Side Upper Receiver is a stripped upper designed specifically for AR-9 builds, providing a clean and streamlined profile without the forward-assist feature. This slick side design not only enhances the aesthetic appeal of your build but also reduces weight, allowing for quicker handling and maneuverability. Builders often choose this upper for lightweight pistol caliber carbine setups, where both performance and style are important.
