The Daniel Defense DDM4 V7 Upper Receiver Group (Daniel Defense part no. 23-128-02339-047) is built around a cold hammer forged 16-inch barrel and a DD-improved flash suppressor. A mid-length gas system gives smooth, reliable cycling with less wear on moving parts. The free-floating MFR 15.0 M-LOK handguard saves weight and adds cooling, ergonomics and modularity. Seven M-LOK positions and an uninterrupted 1913 Picatinny top rail leave room for sights, optics and accessories. It is the standard-profile V7 upper for a builder who wants a proven carbine-length upper.
