Daniel Defense M4A1 556 Upper FDE RIII M-Lok Rail 14.50" Barrel - 23-004-01097-011

Daniel Defense M4A1 Upper

The M4A1 upper receiver group with FDE RIII M-Lok rail; 14.5” cold hammer-forged barrel; DD extended flash suppressor; DD M4A1 RIS II handguard; DD rail panels; ambidextrous GRIP-N-RIP charging handle; and M16 profile bolt carrier group.

Featured on the Daniel Defense M4A1 upper is a cold hammer-forged barrel with a 14.5” M4 profile which, for fast handling and accuracy, is paired with an M-Lok rail in flat dark earth color. The DD rail panels are made from Santoprene, and are heat resistant to 300o F. A DD flash suppressor made of 17-4 PH stainless steel and salt bath nitride-finished for enhanced wear and corrosion resistance is pinned and welded to the barrel on this DD 14.5” upper, and this helps to reduce the muzzle flash from the weapon to preserve the shooter's night vision.

The GRIP-N-RIP charging handle on the DD M4A1 upper is designed to be independently ambidextrous to accommodate both left and right-handed shooters; featuring heavy duty stainless steel roll pins, it is also Type III hard coat anodized just like the DD M4A1 RIS II handguard for durability.

Sporting indexing marks and M4 feed ramps, the Mil-Spec upper receiver is CNC-machined of 7075-T6 aluminum. An M16 profile, Mil-Spec MP-tested, chrome-lined bolt carrier group comes standard with all Daniel Defense 14.5” upper receiver groups, and this BCG features a properly staked gas key.
