Daniel Defense M4 URG MK12
The Daniel Defense M4 URG MK12 Upper Receiver Group is constructed around an 18-inch Stainless Steel barrel with a chamber created during the Cold Hammer Forging process, which ensures the most precise alignment of the chamber to the bore possible. This, along with being salt bath nitride finished, equates to unprecedented accuracy and durability. The MK12 barrel is engineered with a rifle-length direct impingement gas system and utilizes the MK12 gas block, which is built to Crane Specifications for USSOCOM. The MK12 gas block is precision CNC machined from 416 stainless steel and Black Oxide Coated.
The Daniel Defense M4 URG MK12 is fed with a M16 profile bolt carrier group and uses a Vltor Mod 4 charging handle for ease of operation. The upper receiver is equipped with a free-floating DDM4 Rail 12.0™ quad rail for allowing your choice of optics and accessories and is finished off with a Daniel Defense Improved Flash Suppressor.
