Details
The Daniel Defense MK18 Pistol is inspired by the original MK18, which has been extremely popular within the Law Enforcement and Special Operations communities. This firearm is classified as a Pistol and not a Short Barreled Rifle (NFA regulated items require ATF approval and a tax stamp). The Daniel Defense MK18 Pistol features the railed forend Daniel Defense currently provides to USSOCOM and a 10.3” Cold Hammer Forged Barrel, the same length commonly used for CQB operations. The MK18 RISII features our patented 6-bolt Bolt-Up System and has been rigorously tested prior to fielding by USSOCOM. This pistol comes equipped with the SB Tactical SBA3 Pistol Stabilizing Brace with 5 positions of adjustability and integral, ambidextrous QD swivel attachment point. 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.

DD ClassicThe Mk18 is my favorite gun. The RIS2 quad rail feels great, stays cool during mag dumps (I keep the rubber grips on), and is rock solid. The grip-n-rip charging handle does its job and keeps gas out of my face.
If I could only keep one AR15, this would be it.Posted on

Great Quality, Great GunI didnt understand the price, until i actually had the gun in my hands, everything about screams amazing quality, besides the fact that the recoil goes straight back, the gun is super light, the gun has a great rail, the rail grips are just icing on the cake, some manufacturers put polymer rails on the gun, to me this rail feels like its made of metal, i got the fde, the brown rail, the picture doesn't do justice for the gun, once i got it from my local gun store, the brown rail actually looked quite nice, i may add a brown charging handle and pistol grip in the future to add more of the brown it has, and then obviously the cold hammer forged barrel makes it last a really long time, ill prob never put as many rounds as its rated for, this is my first daniel defense, ill definitely be buying another one of their guns or atleast one of their barrels in the future for when i decide to get a 300 blackout

Short package-stout partner!I’m an older avid shooter, do ridealongs with my local sheriffs office, and tons of plinking. I carefully compared DD to many others. Fit, finish, and performance (other deputies) led me to choosing the MK18 pistol on a blind first DD purchase. Could not be happier, or more CONFIDENT in my weapon I’ve chosen. Accurate with good trigger. Stowage and handling in a vehicle (patrol or personal) is perfect. Lightweight and easy to operate. Protect your hearing-suggest a blast deflector on the end as it can be ferociously loud being this short. A DD offset light mount, Vortex 3X spitfire, Surefire Warden and mod1 tailhook takes this to a hard partner level at the house, in the field, and on wheels. And best part-its always fun to shoot! DD mags are top shelf too!

Another Great DD ProductThe MK18 is one of the coolest guns around. It looks menacing with the quad-rail system which seems to be offered less nowadays. My MK18 is equipped with an Aimpoint PRO, MAGPUL AFG, and hanging off the front is a Streamlight TLR-1 HL that has just enough picatinny to attach for great illumination of the surroundings. It is a blast to shoot, extremely accurate. My example is zeroed at fifty yards, as my PDW is the go-to for anything CQB in nature. I would definitely recommend this gun to anyone out of the fleet that DD offers as a very well rounded weapon capable of handling both long range and close quarters interactions effectively.
