MK12 (Daniel Defense Tornado®)

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 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.  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 allowing for 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.  This precision rifle comes finished with Daniel Defense Tornado Cerakote and is furnished with the rugged and comfortable Daniel Defense Buttstock and Pistol Grip.

Good balance, great trigger.
Just purchased. Fired two mags, sweet. Next week I will compare it to my Sig M400.

My favorite m4
As usual beautiful fit and finish. Very smooth and accurate. Trigger is awesome. This rifle will reach out and touch something. My favorite 5.56 so far...ddv11 pro next

Have shot 556 and 223, both very accurate. Love this weapon

MK12 Review
Purchased this rifle a month ago. Fit and finish are excellent. Handling of this rifle is still relatively easy despite the 18 barrel. Was able to achieve near 1 MOA groups with match ammunition at 100 yards with low-mid quality 1-6 power optic. Would recommend this product and this company; superb customer service and top-notch quality. The sum of this rifle's parts make it worth the price.

Great Rifle, wish I owned another!
Accurate, outstanding quality. I own several other rifles, M1A, 45-70, Henry Golden Boy 22LR and I must say I really like this AR. Got it before the ban in Calif :-)
Review by Califboy / (Posted on 4/27/2017)
you gotta like it
I am very pleased with the accuracy of this rifle. The 77 grain Black Hills Ammo make for exultant coyote weapon or just plan shooting out past 100 yards.
Review by Neon / (Posted on 4/26/2017)
Smooth, Accurate, Precision Rifle
This was my very first AR I purchased.
Very accurate, very smooth!
Amazing precision rifle
Review by Black_Hammer / (Posted on 4/4/2017)
Quality and Accutacy in out of the box
Quality is unmatched, accurate is an understatement. 5 rounds with a patrol scope 1 1/4 group and 100 yards awesome.
Review by Andy / (Posted on 2/7/2017)
Accurate out of the box
My 1st AR & my first DD. I was hesitant about accuracy with an AR being use to a bolt action w/ a matchgrade barrel. With 1" separation w/ 55gr Federal ball ammo at 100 yards & 1/2" separation w/ 77gr Blackhills TMK at 100 yards (bench & prone) this rifle exceeds my expectations. Equipped with NXS 2.5-10×42 & GPS.02.

My favorite rifle
Most accurate AR I have shot . The usual DD fit and finish e.g.impeccable. I will buy a spare as soon as I can.
Review by Vato loco / (Posted on 12/13/2016)
Unbelievably accurate. Built like a precision machine.

Remarkable rifle I love it!
Review by Weekend warrior / (Posted on 11/13/2016)
A fabulous rifle
After receiving my DDM4A1, I began researching my next Daniel Defense purchase. I was torn between the DD5 V1 and DDM4 MK12. I decided to stick with the 5.56 caliber. Just took delivery of the rifle up. I had high expectations based on my M4A1. My expectations were exceeded. The finish is superb. I have mounted the scope & am anxiously awaiting time at the range. My son-in-law is coming to visit & will be bringing his new Daniel Defense DDM4 V5 he got this week after seeing my M4A1. We are a Daniel Defense family!
Review by Hugh R Daniel, MD, FACS / (Posted on 10/6/2016)
A Great "Grey" Rifle
This is a precision rifle that both looks great & is fun to shoot. Fit & finish is second to none. I have only reached out to 100 yards to date, but accuracy is amazing. Sub 2" patterns now but sub 1" will be possible with some practice. Price is on the high side but I feel t's still a very good value overall. 2 stage trigger works great. I mounted a 6-24x50 quality scope, a 6"-9" bipod, an anti cant bubble level, a 1 (or 2) point sling along with a Daniel Defense vertical grip. What a fantastic setup. Last time at the range, a fellow shooter commented to me that the Daniel Defense rifles were amongst the elite. I could not argue with him. Totally satisfied with this rifle.

Love it!
The quality of this rifle really shows. I was hesitant on spending this much money on my first AR 15 gun, however, once you hold this thing you will be able to easily understand why it's a couple steps above your on the shelf sporting goods store rifle. The DD fixed sights were a perfect pair for this weapon as well....first time shooting it I had a 2 inch group from 50 yards... And I am very novice in the shooters world. Love it!
Review by Rexdog84 / (Posted on 4/13/2016)
Great product thank you.
I give the MK12 all high marks the product is well put together no problems at all. I would recommend it to my friends. If you could make the case a little bit wider to acomadate a scope that would help so you don't have to buy another case for it.
Review by Dennis Rogalla / (Posted on 4/6/2016)
Must to own one!
Very accurate, almost no recoil, soft trigger and light. But all models are little bit above it's worth! I bought this model, adding Muzzle Climb Mitigator Gen II, tornado grip, sight and for the price should come with it!!
Review by El Romo / (Posted on 4/6/2016)
Just awesome
Very nice shooting rifle better than my M-16A2 and M16-A4. glad I was able to get one, my local shop sells out of them as soon as they come in.
