The evolution of the SPR comes home to Daniel Defense in the MK12.  Born of necessity, raised in the Army’s Marksmanship Unit and refined to Daniel Defense Mil-Spec+ standards, it is now available. The MK12 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 rifle is fed with a M16 profile bolt carrier group and uses a BCMGUNFIGHTER 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. The MK12 was designed from the ground up to be a precision rifle, therefore it required certain refinements.  We equipped it with the Geissele SSA 2-Stage Trigger to give the marksman an advantage delivering precise fire to the target.  The MK12 is also furnished with the rugged and comfortable Daniel Defense Buttstock and Pistol Grip.

The Colt 6940 monolithic rifle is one of the most popular tactical rifles on the market, and usually one of the hardest to find.  The monlithic design upper is built tough for tactical environments, and shares a common lower receiver with the rest of the M4 and 6920 family of Colt rifles.  The Mil-Spec hammer and trigger pivot pins, a Magpul MBUS backup sight and a folding front sight for enhanced optical solutions, and a straight gas tube and a removable lower rail which provides modularity for under mounting accessories. The patented one-piece monolithic upper receiver incorporates a continuous Mil-Spec rail from the rear of the upper receiver to the front sight. This feature affords unmatched repeatability for mounting optical systems, not found with separate handguard rail systems. Designed with accuracy in mind, its true free-floating barrel provides the enhanced accuracy necessary for long-range acquisition capability.

The Ruger AR-556 rifle is a gas impingement driven, box magazine fed, autoloading rifle. The mechanism utilizes the gas from the firing of the round to drive the bolt carrier rearward and rotate a bolt that locks into the barrel. The AR-556 rifle can be field stripped without the use of tools and breaks down into basic subassemblies. The safety, located above the trigger on the left side of the lower receiver, blocks the trigger and permits the bolt carrier to be cycled with the safety in the on or “SAFE” position. A bolt catch mechanism is provided for convenience in holding the bolt open for loading and inspection. The firing pin is retracted mechanically as the bolt starts to unlock and the rifle will fire only when the bolt is locked.
