DD M4V7 UPPER 556 16″ MLOK BLK

Description

The DDM4 V7 Upper Receiver Group is built for the AR-15 shooter who wants a complete, ready-to-run upper from a single source rather than assembling components piecemeal. It ships with a bolt carrier group and the GRIP-N-RIP charging handle already installed, so the only thing left is a lower.

The barrel is Cold Hammer Forged from Chrome Moly Vanadium steel, a process that work-hardens the bore and prolongs service life under sustained fire. A chrome lining on the bore and chamber adds corrosion resistance and eases cleaning after high round counts. Daniel Defense cuts the rifling at a 1:7 twist, which stabilizes heavier projectiles in the 62–77 grain range that many carbine shooters favor for terminal performance; lighter 55-grain loads also run reliably at that rate.

The mid-length gas system is a deliberate choice over a carbine-length alternative. Drawing gas from further down the barrel reduces port pressure at the moment the bolt unlocks, which softens the impulse felt at the shooter’s shoulder and slows the rate at which components cycle. The result is a more controllable firing cycle and reduced long-term wear on the bolt carrier group.

The MFR 15.0 free-floating handguard is machined from 6061-T6 aluminum and attaches via M-LOK at seven positions around the circumference, keeping the profile slim while giving the shooter a full fifteen inches of rail-compatible real estate. Because the handguard makes no contact with the barrel, it cannot deflect point of impact when a support hand applies pressure or a sling exerts tension. The upper receiver itself is CNC-machined from 7075-T6 aluminum with M4 feed ramps and Type III Hard Coat Anodizing. Sights are sold separately.
