Over-the-Top Quality. The AR-15 represents the most successful weapon's platform in history. Never before has a military firearm evolved so rapidly, so completely and in so many directions. It has often been said that the AR-15 is the erector set of the shooting world, being set- up, changed, accessorized, rethought, rebuilt and put together to suit almost any need.

This precision instrument has successfully served as a military, sniper, law enforcement, defensive, hunting, competition and target rifle in more calibers and configurations than one can possible imagine. No other firearm can make that claim. Many argue that it is the most versatile military small arm ever invented and after 60- years of service, is still going strong today as our nation's primary battle rifle.

Daniel Defense is a privately owned manufacturer specializing in custom built AR-15's and tactical accessories with facilities located in both Black Creek, Georgia plus Ridgeland, South Carolina. Precision crafted from top quality materials with meticulous attention to detail, the Daniel Defense M4 carbine has proven to be a benchmark of excellence in the shooting industry.

In fact, the company is very highly regarded among military, law enforcement, tactical professionals and civilian marksman alike. For design and development, the MK12 underwent rigorous torture testing, which included simulations for harsh desert environments, water submersion, shrapnel blasting, explosion blasting, being run over by a vehicle and then dropped from heights up to 100 feet -- followed by function and accuracy testing.

At the heart of the design is a barrel engineered with a rifle-length direct impingement gas system that utilizes the MK12 gas block, which is built to Crane Specifications for USSOCOM. Gas is tapped from the barrel as the bullet passes by the port located above the rifle's low profile front gas block, which is CNC machined from 4140 steel and salt bath nitride finished. The gas then rushes into the port and down a gas tube located above the barrel into the upper receiver.

From there, the gas tube funnels into the bolt carrier. This gas system unlocks the bolt and begins the cycling process, but only after the bullet has exited the barrel. Direct impingement has several advantages over gas piston systems. For semi- automatic rifles with a barrel length of 16" or greater, impingement AR-15s are lighter, easier to free float the barrel, typically more accurate and much less expensive to manufacture.

Daniel Defense is now only one-of-five companies worldwide producing cold hammer forged barrels. 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 salt bath nitride finished, equates to unprecedented accuracy and durability. The barrel is then High Pressure Magnetic Particle Inspected, which is a non- destructive test consisting of firing proof loads to identify any possible imperfections such as fractures, inclusions, stringers or voids.

The barrel has a 1:7" twist rate that is fast enough to stabilize heavy bullets like the 77gr match round, but still capable of accurately firing standard 55gr ball ammo. The Daniel Defense MK12 is chambered for 5.56 NATO cartridges , which allows you to safely fire both full power 5.56 loads or lower powered .223 rounds interchangeably without adjustment to the gas system.

The M4 feed ramps ensure proper feeding of ammunition to help eliminate malfunctions, even during rapid fire. The muzzle device is a Daniel Defense flash suppressor constructed of 17-4 PH stainless steel that is salt bath nitride finished.

A 6- position Daniel Defense "Soft Touch Overmolded" collapsible stock is constructed of glass filled polymer and allows the shooter to adjust length of pull to their personal preference. A DDM4 12.0 free- float quad rail forend provides attachment points for lights, lasers or a tactical foregrip. To prevent abrasion to the hand during tactical handling exercises, three heat resistant Santoprene Rail Ladders are included. In addition, both front and rear Soft Touch Overmolded vertical grips are included that provide control and improved handling.

All rifle dimensions are mil-spec. The MK12's bolt has been magnetic particle inspected, shot peened and pressure tested to ensure that it's structurally sound and will not fail. The rifle is fed with a M16 profile bolt carrier group and uses a Vltor Mod 4 charging handle for ease of operation.

Both upper and lower receivers are forged from durable, lightweight aircraft grade CNC machined 7075-T6 aluminum that is then Type III hard coat anodized per military spec to provide wear and corrosion resistance. Due to the fact the bolt locks into a steel extension on the barrel and not the receiver, the MK12 can easily use such lightweight construction materials without sacrificing structural integrity.

The rifle weighs in at just 7.41 pounds and is a fast handling rifle. It includes one 30- round Magpul PMAG. All steel parts wear heavy mil- spec phosphate coatings, which include the barrel. Build quality is outstanding -- there is zero play between the upper and lower receiver, plus the CNC machined parts fit together like the gears found inside a finely made watch.

The full- length flat- top Picatinny rail provides a versatile mounting surface for standard the scout length eye relief optics, but no sights are included.. In the rare event a round fails to go into battery, the rifle is equipped with a forward assist. Similarly, a spring loaded receiver dust cover is designed to keep out dirt and other debris from entering the action, but instantly opens after the first shot.

For long range accuracy, a Geissele SSA® 2-stage trigger is crisp and breaks cleanly. For repair, the rifle is backed by a 100% satisfaction guarantee against defects in original materials and workmanship. Overall, the Daniel Defense MK12 is a highly accurate, well built, mil- spec AR-15 rifle over-engineered for a lifetime of reliable service.
