This complete upper features a matte black finish, low-profile gas system, and full-length top rail ready for your choice of optics or iron sights.

Configured as a dedicated upper receiver assembly, this kit is ideal for upgrading an existing AR-15 or M4 lower into a versatile general-purpose rifle for training, range use, or practical competition. The 16.1" barrel offers a balanced blend of handling and ballistic performance, while the free-floated handguard supports accessory mounting without adding unnecessary bulk. Built by Colt, it reflects the manufacturer’s long-standing reputation for dependable performance and consistent craftsmanship.
