Daniel Defense AR-15 DDM4v2 A3 Flat-Top Upper Assembly 5.56x45mm NATO 1 in 7" Twist 16" M4 Barrel Chrome Lined CM with DDM4 7.0 Quad Rail Free Float Handguard, Flash Hider
The DDM4v2 features the new DDM4 7.0 Free Float Quad Rail Handguard that extends all the way to the CNC-Machined Front Sight Base/Gas Block, providing ample room for mounting tactical accessories and greater accuracy potential by isolating the barrel from outside influences. The DDM4 Rail combines the best features of Daniel Defense's previous handguard designs to create an entirely new and improved platform. The 1-Piece Lower Rail of the handguard has been located closer to the barrel for an exceptionally slim, compact exterior footprint that is more comfortable and ergonomic to hold in the off-hand. The M4 rail is secured to the upper receiver with a new Bolt-Up System using 4 steel fasteners for rock solid stability and repeatable positioning of rail mounted accessories, and includes 4 Integral Quick Detach Sling Swivel Sockets for a multitude of sling mounting options. The DDM4v2 Upper comes complete and ready to fire with a Daniel Defense A1.5 Detachable Rear Sight, charging handle, Daniel Defense Flash Hider, 3 low profile ladder rail covers and a Daniel Defense Vertical Fore Grip.
