The Daniel Defense DDM4v7 Complete AR-15 Upper Assembly features a premium, Cold Hammer Forged Barrel made from Mil-Spec 4150 Chrome-Moly Vanadium Steel that is Chrome Lined for durability and corrosion resistance. M4 feed ramps are incorporated into the barrel extension and upper to enhance reliable feeding, while a true 5.56x45 NATO chamber ensures that both commercial and higher pressure surplus mil-spec ammunition may be safely used. The bolt and carrier both pass a thorough Magnetic Particle Inspection (MPI) test for guaranteed structural integrity, and the gas key is properly staked to its mil-spec bolt carrier. All steel parts feature a heavy Mil-Spec Phosphate finish for superior corrosion resistance and durability, while aluminum parts are Type III Hard Coat Anodized.

The DDM4v7 comes equipped with the new Daniel Defense MFR 12.0 Modular Rail Handguard system for adding tactical accessories while also free floating the barrel for increased accuracy potential. With the exception of a full length, uninterrupted top rail surface that accommodates virtually any desired sighting arrangement, the MFR's body is a small diameter modular tube that will accept add-on rail sections only where the shooter needs them for accessories. This allows the handguard to remain snag-free, uncluttered and devoid of unused rail space, making for a more comfortable off-hand point of contact than full-length quad rail designs. The 12" handguard covers a pinned, low profile gas block at the Mid-Length gas port position, offering the dual benefits of a longer sight radius and increased gas dwell time for a softer recoil impulse upon firing. This DDM4v7 upper comes complete and ready to shoot with a charging handle assembly, Daniel Defense Flash Hider, and 3 Modular Picatinny Rail Sections.
