Great gun
Great gun just overpriced I can build something with alot better parts for about the same price
Review by Bws2007 / (Posted on 8/7/2018)
If I had the money, I would order 2.
Love the rifle! Hate the wait for NFA! Wish it came with more than one mag. For the cost at least 2 to 3 mags would of been nice. Other than that, I still would order it.

Awesome machine, runs like a champ, accurate and dependable, always the envy of firing line

Great Weapon!!!
Love the weapon, to pricy I believe it could be in the $800.00 range.
Review by WarGasm / (Posted on 5/20/2018)
Great specs, a little on the high price though.
Oh, if only there was a monthly pay plan!

Steep in price
Excellent firearm, steep in price
Review by JBOOTH5 / (Posted on 3/12/2018)
Too expensive
D.D. is well known for putting out a quality product, but there's no way that I could afford to pay over 2200 dollars for such a rifle.
Especially when you consider that I could (almost) buy 3 S&W 15 carbines for the same amount.

It’s amazing how it’s handled
It’s amazing

Top Quality
My go to rifle. HD and duty.
Review by Alacop / (Posted on 1/24/2018)
MK18, my second wife...
8 shots out of the box and it was dialed in, in less than one mag we were plinking 10" steel at 250 yds with an Aimpoint T2 red dot on top.
Only negative is the safety is unusually very stiff! That will hopefully smooth out with use. Love it overall
Review by Joemama / (Posted on 1/22/2018)
I'm wondering if te dd mk 18 is legal in California despite the new gun law.
Are they legal in California?
Review by Kc / (Posted on 1/5/2018)
Outstanding SBR.
Outstanding build! My son is a Navy SEAL and he told me about this weapon. He said for me to get one if I could. I did and cannot be more impressed. This handles incredibly well and is easy to maneuver with through any type of competition. Accuracy is fanominal and the Precision construction says it all. It makes my MP5 and MPX stay in the safe.

Breathe taking
Dream come true

Absolutely positive
Review by Quicksilver2008 / (Posted on 5/13/2017)
Want another.
Wonderful weapon. eats everything I feed it, never a FTF. Worth every bit of scratch it costs.

There is no substitute
I love my MK18 It's the greats rifle I've ever put hands on
Review by That Guy / (Posted on 12/21/2016)
One of the best rifles made period!
Worth every penny! Some of the best rifles made period. I use the Mk18 upper at work with the Colt lower and a geissele trigger, and I own the DD Mk18 and Mk11, and I wish my work gun was a complete DD rifle. On top of the quality of the products they make they hire and employ alot of veterans especially former special operations soldiers.

the best
love it!
Review by earl / (Posted on 9/5/2016)
I have owned AR style rifle for almost a decade now. It seems that everyone I buy I have to modify in some way to make better. It usually means upgrading grips/trigger guard/buttstock.....even cerakoting them a different color. I love that DD came out with a weapon that for the first time ever... I don't have to f*** with. It is perfect right out of the box!!! I love my Milspec+ SBR. I sold all of my other rifles and am absolutely content just having this one. YOU WILL TOO!!
Review by Skarbek Arms LLC. / (Posted on 9/5/2016)
Stop Waiting and Buy a DDM4 MK18!
I wanted this rifle for about two years before I bite the bullet and got a trust and purchased it. It is by far my favorite firearm I own. The fun factor is through the roof. I added a Crux Suppressors Nemesis can and make a perfect home defense weapon. It also get a ton of attention when I go out shooting. The MilSpec+ coloring is great on the eyes. I had a previous MagPul stock & grip Ambush 5.56 and the new Daniel Defense stock and grip feel great!

A rifle to bet your live on.
Meet my new best friend. Finally broke down and a got a SBR. Plenty of brands to choose from and to be honest I took a chance with Daniel Defense. If you have not held a Daniel Defense in your hands please do so. Talk about love at first sight and the way the rifle performs is an experience you have to have personally in order to appreciate. Is it expensive? Yes. However, "quality" is always going to cost you a little more. The quality is built in this rife and if you do not believe me watch a few YouTube videos on the Daniel Defense torture test. No No NO I have not and will not do this to my rifle. To me "Value" means what price do I put on my life and that of my family. Like I said above "meet my new best friend" a Daniel Defense MK18 (Mil Spec+) 5.56.
