The Daniel Defense DDM4 V7 upper receiver group (Daniel Defense part no. 23-128-02339-047) is a complete AR-15 upper built around a cold hammer forged 16-inch barrel chambered in 5.56mm NATO. Daniel Defense pairs the barrel with a mid-length direct impingement gas system, a free-floated MFR 15.0 M-LOK handguard and a GRIP-N-RIP charging handle. A DD flash suppressor sits on the muzzle, and an M16-profile bolt carrier group is included, so the upper is ready to drop onto a compatible lower. Sights are sold separately, which leaves the choice of optic or iron sights to you. It is a straightforward way to build or refresh a quality 16-inch carbine.

• The barrel is 16 inches with a Government profile, cold hammer forged from chrome moly vanadium steel, chrome lined and phosphate coated.
• The twist rate is 1:7, a fast twist that stabilizes heavier bullets.
• The gas system is mid-length direct impingement with a pinned low-profile gas block machined from 4140 steel, for smooth cycling and reduced wear.
• The handguard is the Daniel Defense MFR 15.0 in 6061-T6 aluminum, free floated, with M-LOK attachment points along 7 positions.
• An uninterrupted 1913 Picatinny top rail runs the length of the upper for optics and sights.

• The bolt carrier group is M16 profile, mil-spec MP tested, chrome lined, with a properly staked gas key.
