The Daniel Defense Assembled Upper is a factory-built upper receiver assembly intended for sport shooting, range use, and training on AR-style platforms. It is offered as a finished upper component to simplify building or upgrading an AR-pattern rifle when paired with a compatible lower receiver.
This assembled upper is produced to Daniel Defense quality standards and is designed to integrate with common AR-15 pattern lowers. It provides a straightforward way to replace or upgrade an upper without sourcing multiple individual parts.
Check fitment and local regulations before purchase. This listing describes the assembled upper component only — a compatible lower receiver, buffer system, and other items may be required for a complete firearm.
