AR-15 Complete Uppers

AR-15 Complete Uppers provide a fast and convenient way to upgrade or complete your rifle without the need to source individual upper components. Each upper assembly comes fully built and ready to pair with a compatible AR-15 lower receiver, allowing you to change calibers, barrel lengths, or configurations quickly. While labeled “complete,” some uppers may include a bolt carrier group and charging handle, while others do not—so be sure to review the product description for exact contents. With a wide selection of calibers, profiles, and handguard styles, complete uppers offer a simple, reliable, and cost-effective solution for building or upgrading your AR-15.
