The Colt AR-15 5.56x45mm upper receiver assembly with 16" barrel and Centurion CMR 13" M-LOK handguard gives you a ready-to-run upper that drops straight onto your AR-15 lower receiver. Built on Colt's Enhanced Patrol Rifle platform, this upper ships as a complete assembly designed for shooters who want a practical, no-fuss setup without piecing together individual components. The 16" barrel length strikes the balance most hunters and range shooters want—fast handling without sacrificing velocity—while the free-floating Centurion handguard keeps your barrel unencumbered for consistency shot to shot.
The barrel itself is chrome lined and button rifled with a 1-7 twist rate, giving you the rigidity and longevity Colt barrels are known for. A phosphate finish protects against corrosion during field use and training. This upper arrives complete with an M16 bolt carrier group and charging handle, so you're not hunting down parts before you can function-test it. If you're dropping this onto an existing lower, you're ready to go to the range or field.
The Centurion CMR handguard brings modern ergonomics to the platform. Its 13" length provides plenty of real estate for optics, lights, or other tactical accessories via M-LOK slots, while keeping the overall package reasonably compact. Whether you're building a hunting rifle, a practical duty setup, or upgrading an existing build, this Colt upper delivers the kind of straightforward reliability and functionality that has made the AR-15 the most versatile rifle platform in America.
