The Daniel Defense DDM4 V7 Upper Receiver Group (Daniel Defense part no. 23-128-02339-047) is a complete 16-inch AR platform upper chambered in .223 Rem/5.56 NATO, built around Daniel Defense’s proven DDM4 V7 handguard system in M-LOK configuration. It gives a builder or existing AR owner a drop-in way to add a genuine Daniel Defense barrel and handguard to a matching lower without sourcing individual components separately. The barrel runs a 1-7 twist, well suited to the heavier, higher-BC 5.56 projectiles that have become common for both duty and precision use, and the upper ships without sights, leaving optic choice entirely up to the builder.
