The Daniel Defense M4 V7 Upper Receiver Group is built around a Cold Hammer Forged 16” Government profile 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 XS 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 Upper Receiver Group has plenty of room for the sights, optics, and accessories the user may require. All Daniel Defense complete upper receiver groups come standard with a bolt carrier group and charging handle.
