Expo Arms
Overview
The Expo Arms AR-15 Billet Slick Side Upper Receiver is a stripped receiver designed specifically for the AR-15 platform. Its slick side design eliminates the forward-assist feature, resulting in a streamlined profile that appeals to builders looking for a clean aesthetic while maintaining functionality. This upper receiver is often used in lightweight or minimalist builds, where every ounce counts and simplicity is key.
