Daniel Defense URG Complete Upper Receiver, DDM4 V7 Pro, 5.56 NATO, 18", Black The Daniel Defense DDM4 V7 Pro Upper Receiver Group was designed for competitors who want to win multi-gun matches. It is built around an 18 inch cold hammer forged S2W profile barrel and a rifle-length gas system, giving you the speed, control and precision needed for long stages that mix close targets with longer shots. This is part number 23-128-20044-047, finished in black. It arrives as a complete upper receiver group with the bolt carrier group, GRIP-N-RIP charging handle and an M-LOK vertical grip, ready to pin onto your lower. An 18 inch competition upper with rifle gas and a full-length 15 inch M-LOK rail. 18 Inch S2W Barrel and Rifle Gas Daniel Defense hammer forges its barrels in house from chrome moly vanadium steel. Cold hammer forging packs the steel tight around a mandrel, which gives long barrel life and consistent accuracy. Each barrel is chrome lined, Mil-Spec heavy phosphate coated and HP/MPI tested. The V7 Pro uses the 18 inch S2W profile, Daniel Defense's own heavy barrel contour, with a 1:7 twist that stabilizes a wide range of 5.56 and .223 bullet weights. The added weight up front steadies the muzzle for fast follow-up shots. The rifle-length gas system runs through a pinned low profile gas block of hardened 4140 steel. A longer gas system means a softer, flatter recoil impulse, and that is what keeps your dot on target during fast strings. The Gen II Daniel Defense Muzzle Climb Mitigator, 17-4 PH stainless steel with a salt bath nitride finish, helps hold the muzzle down even more. MFR 15.0 M-LOK Handguard and Vertical Grip The Daniel Defense MFR 15.0 handguard is CNC machined from 6061-T6 aluminum and Type III hard coat anodized. It free floats the barrel, runs cool and light, and gives you M-LOK slots along its length plus a continuous top rail for your optic. The long rail lets you reach your support hand far forward, which is the grip most competitors use to drive the gun between targets. A Daniel Defense M-LOK vertical grip in glass-filled polymer is included, so the upper is ready to run as soon as it is mounted. Receiver, BCG and Charging Handle The upper receiver is Mil-Spec with indexing marks and M4 feed ramps, CNC machined from 7075-T6 aluminum and Type III hard coat anodized. The bolt carrier group is M16 profile, Mil-Spec MP tested and chrome lined, with a properly staked gas key. The GRIP-N-RIP charging handle has independent latches on both sides, so left- and right-handed shooters can run the rifle the same way. Installation and Compatibility This upper receiver group fits any Mil-Spec AR-15 lower receiver. Install it with the two takedown pins, then function check before live fire. Use a buffer and spring suited to rifle-length gas in your lower; Daniel Defense does not include buffer parts with an upper group. Lower receiver, stock, magazine and optics are sold separately. An upper receiver is not the regulated part of an AR-15, so it can ship directly to you where state and local law allow.
