Daniel Defense M4 V11 by Alejandro Meza, Verified Owner, April 10, 2018
It’s very strong and very light. I’m very impressed with how well and how accurate it shoots. I have the upper along with a BCM Lower. Very happy with it’s performance. I run it with a Holosun 510C and it’s definitely great together

Great Upper by Jim, April 11, 2018
I purchased this pruduct for a lower I assembled and I have to say I’m very impressed with it. It’s accurate, light, and I have had zero issues so far. Optics Planet processed my order quickly and I would order from them again in the future.

Product Info for Daniel Defense DDM4 V11 Upper Receiver Group 5.56 NATO 16in Government Profile Barrel SLiM Rail 15.0

The Daniel Defense M4 Carbine V11 Upper Receiver Group was designed for shooters who prefer the benefits of the KeyMod system integrated in the new SLiM Rail. KeyMod is a recoil resistant, two-part, direct attachment method for accessories that offers outstanding "return-to-zero" when accessories are removed and reinstalled. The new SLiM Rail 15.0 offers incredible weight savings as well as superior cooling, ergonomics, and modularity while maintaining the strength and durability expected from Daniel Defense. The long, 15" rail gives operators the option to have the support hand extended out close to the muzzle allowing them to drive the gun more precisely and prevents over travel when transitioning between multiple targets. This combined with our mid-length gas system, which is known to have a smoother recoil impulse, allows for quick, but precise rapid fire. An uninterrupted picatinny rail on top and KeyMod attachment at 3, 6, and 9 o'clock, ensures plenty of real estate for optics and accessories and allows for maximum sight radius for accurate shooting with rail mounted iron sights. The DDM4v11 URG is equipped with a free-floating, Cold Hammer Forged, 16" Government profile barrel. 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.image
