The Daniel Defense MK18 Pistol is a variation of the MK18 SBR, 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.

  2. Another Great DD Product
    The 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.

  3. MK18 pistol. Buy one today, you won’t be disappointed.
    If you’re looking to get an AR pistol don’t miss out on this one. I have 3 and they are a blast to take out to the range. I also have 2 M4A1’s (mil-spec brown an spruce green), Along with an M4 300 blackout and an extra upper!! To say I like Daniel Defense is an under statement. They are quality products from a quality company. And, they’re made in the USA!

  4. More fun than an octopus in your jockstrap
    Absolutely my favorite gun/pistol. It was my first AR-style gun, but remains my favorite. I am not an "operator", just a plinker, but have put thousands of rounds through this boomstick. Zeroed in at 25 yards with a Sig Romeo 4s, but even as a novice this gun makes me a stone cold zombie killer out to 100+ yards. It would be my go-to gun for home defense as its short length is very easy to move around in confined spaces. Only single malfunction was ammo-related, not the gun. There are tools that make one a cheater, and this is one of them.
