Daniel Defense DDM4V7 Black 5.56 NATO 16" Upper Receiver Group 23-128-02339-047

The Daniel Defense DDM4V7 23-128-02339-047 Upper Receiver Group is the complete upper solution for AR builders and Daniel Defense owners who want factory DD quality in a standalone upper — constructed around a 16-inch cold hammer forged barrel and equipped with the extra features and component quality that Daniel Defense products are specifically known for delivering at every price point they offer.

The DDM4V7 Upper 16 cold hammer-forged barrel delivers the dimensional consistency, surface finish quality, and long-term durability that cold hammer forging produces over button-rifled alternatives, a superior barrel construction that Daniel Defense uses across its lineup. The interior of the barrel is chrome-lined for superior service life, maintaining accuracy and corrosion resistance through the high round counts and hard use that serious AR shooters put their platforms through. The barrel is topped with a Daniel Defense improved flash suppressor that greatly mitigates visible muzzle flash — a meaningful feature for low-light and nighttime shooting applications where flash signature matters.

The Daniel Defense DDM4V7 upper mid-length direct impingement gas system with pinned low profile gas block CNC machined from 4140 hardened steel provides the reliable, consistent gas operation that mid-length systems are specifically known for — reduced felt recoil and smoother cycling compared to carbine-length gas systems on a 16-inch barrel, with the low profile gas block keeping the system compatible with free float handguard installation.

The DDM4V7 Upper 15-inch Daniel Defense MFR handguard is remarkably lightweight and ergonomic while providing excellent heat dissipation through extended firing sessions. The full-length Picatinny rail at the 12 o'clock position accommodates iron sights and optics, while M-LOK attachment points around the handguard provide mounting positions for tactical lights, lasers, and other accessories.

The Daniel Defence upper comes standard with a Daniel Defense glass-filled vertical grip and an ambidextrous Grip-N-Rip charging handle.
