The DDM4 V7 LW AR15 style Upper Receiver Group is built around a Cold Hammer Forged 16 inch Lightweight profile barrel, which is two ounces less than a standard V7 barrel, and equipped with a DD improved Flash Suppressor to reduce flash signature. It features a mid-length gas system for smooth, reliable cycling and reduced wear on moving parts. A free-floating MFR 15.0 handguard offers incredible weight savings as well as superior cooling, ergonomics, and modularity while maintaining the strength and durability expected from Daniel Defense. With the M-LOK attachment points that run along 7 positions and an uninterrupted 1913 Picatinny rail on top, the V7 LW Upper Receiver Group has plenty of room for the sights, optics, and accessories the user may require. The independently ambi GRIP-N-RIP Charging Handle accommodates left- and right-handed shooters. All Daniel Defense complete upper receiver groups come standard with an M16 profile bolt carrier group.
