AR-10 Complete Uppers
The AR-10 is the heavy-hitting big brother to the AR-15, engineered to chamber full-power rifle cartridges that offer superior energy and extended range. Selecting a Complete Upper Assembly is the most efficient way to step up to a "large-frame" build, providing a factory-headspaced and test-fired solution that is ready to pin onto your lower receiver.
Whether you are targeting long-range steel, hunting large game, or building a dedicated Designated Marksman Rifle (DMR), these uppers deliver the knockdown power that 5.56 simply cannot match.

Every AR-10 complete upper assembly in our inventory is built to dominate the hunt or the competition, featuring robust M-LOK free-float handguards for maximum rigidity and accessory mounting. We prioritize long-range accuracy by utilizing match-grade 416R stainless steel or 4150 CMV barrels, paired with heavy-duty, MPI-tested bolt carrier groups (BCG) and ergonomic charging handles included in every "Complete" package. From suppressed-ready brush guns to 1,000-yard precision rigs, our uppers are test-fired to ensure flawless operation and consistent sub-MOA performance. Shop our diverse range of barrel profiles and lengths to find the perfect AR-10 upper receiver that balances raw stopping power with modern ballistic excellence.
