The Daniel Defense M4A1 Upper Receiver Group, trusted by USSOCOM for the SOPMOD Block II program since 2005, delivers battle-proven performance for tactical shooters. Built around a 14.5-inch Cold Hammer Forged M4 Profile barrel with a 1:7 twist, chrome-lined and Mil-Spec heavy phosphate-coated, this upper ensures durability and precision. The permanently attached Daniel Defense Extended Flash Suppressor, crafted from 17-4 PH stainless steel with a salt bath nitride finish, enhances muzzle control. The carbine-length gas system and pinned low-profile gas block provide reliable cycling, while the Flat Dark Earth RIS II Picatinny quad rail, CNC machined from 6061-T6 aluminum, offers robust accessory mounting with heat-resistant Santoprene rail panels. The independently ambidextrous GRIP-N-RIP Charging Handle, made from 7075-T6 and 6061-T6 aluminum, accommodates both left- and right-handed shooters for seamless operation. Paired with a Mil-Spec M16 bolt carrier group, this 4.56-lb upper, constructed with a 7075-T6 aluminum receiver and Type III hard coat anodizing, is made in the USA for rugged reliability. Perfect for AR-15 enthusiasts seeking SOCOM-inspired quality, the M4A1 upper is ready for action.
