The Daniel Defense M4 V7 LW Upper Receiver Group is built around a Cold Hammer Forged 16" 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 new independently ambi GRIP-N-RIP Charging Handle accommodates left- and right-handed shooters and is engineered for suppressed fire, with anti-gas features that redirect gas flow upward and away from the face and operator. All Daniel Defense complete upper receiver groups come standard with an M16 profile bolt carrier group.
