Every AR10 upper we sell is professionally assembled, thoroughly inspected, and built to deliver dependable performance with the power and accuracy the .308 platform is known for. Each upper is ready to install and engineered for shooters who demand reliability straight out of the box.
All of our AR10 uppers are compatible with DPMS .308–pattern components, making it easy to pair your upper with the correct lower, bolt carrier group, and internal parts. Whether you’re completing a precision rifle or a hard-use .308 build, these uppers are designed for proper fit, function, and compatibility within the DPMS ecosystem.
We source barrels in a variety of lengths to support the most popular AR10 rifle and pistol configurations. From compact, maneuverable setups to full-length barrels optimized for long-range accuracy and velocity, you can choose an upper that matches your shooting style and application.
Performance starts with the barrel. Our AR10 uppers feature either 4150 CroMoV (mil-spec) barrels for durability and heat resistance, or 416R stainless steel barrels for enhanced precision and consistent sub-MOA potential. Each option is selected to maximize accuracy, longevity, and reliability under demanding conditions.
Whether you prefer a traditional forged receiver or want the enhanced ergonomics of a billet or side-charging design, we offer AR10 uppers to match your build preferences. Choose a classic mil-spec look or upgrade to modern features designed for comfort and control.
