Daniel Defense MK12 Upper Receiver Group 18in 23-142-10035 Caliber: 5.56x45mm NATO, Overall Length: 20 in, $127.00 Off w/ Free S&H

The Daniel Defense 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 DLC 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 new independently ambi GRIP-N-RIP Charging Handle accommodates left- and right-handed shooters and is engineered for suppressed fire, with anti-gas features that redirect gas flow upward and away from the face and operator. 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.
