I picked up one of these rifles this week, and thought I would post an initial review. For those unfamiliar this is the Daniel Defense DDM4V11 series gun with the 15" Slim Rail (KeyMod), and instead of a 16" light weight or govt' profile chrome lined barrel this model uses their 18" S2W salt bath nitrided barrel, plus a few other changes. Fit and finish is good, and if I didn't know better I'd swear the whole rifle has been cerakoted black since all the aluminum bits match each other exactly. The long slim rail is nice, and despite the heavier barrel and total weight of 7.5lbs the rifle balances nicely since the barrel is thickest towards the receiver and the rail is nice and light. I have a Colt M4A1 SOCOM II that weighs the same with a slightly lighter contour barrel under the beefy DD RIS II rail, and frankly doesn't balance as well as the DD.
Furniture is the new Daniel Defense overmold stuff, which I hate the look of, but can't fault the function... in fact it is pretty damn comfortable for me and (huzzah!) the collapsible stock is nice and snug on the buffer tube and doesn't allow my beard hair to get pinched in between. I never knew you could have a beard, and use a collapsible stock that didn't rip hair out of your face. This model comes standard with a Geissele Super Dynamic 3 Gun trigger, which I have used in the past and had issues with in the aforementioned Colt. In the DD this trigger gave me no unintentional doubles, but it does make shooting deliberately for groups more challenging with the upside of being blazing fast on reset. It is a gun game trigger, and will get replaced with a Geissele 2 stage; I'll either sell it off or set it aside as a spare if I decide to play gun games later on. The PRO model also uses the Daniel Defense "Muzzle Climb Mitigator II" muzzle device, between the rifle length gas system and this comp the rifle doesn't display a lot of muzzle movement although strait to the rear recoil seems about the same as any other AR. This muzzle device is blasty and loud though, will probably get pulled off and replaced with a decent hybrid device at some point.
I did a quick accuracy (OK Molon... Precision) evaluation today until sundown when I got kicked off the range, to do this I mounted a Nightforce NXS 3.5-15X50 in a Nightforce Uni-Mount and went to work getting the rifle on paper at 50 yards then moved back to the 100 yard line. I was able to test Winchester M855, Wolf 55gr steel case, and two of my hand loads that have shot well in the Colt and my other DD 18" barrel Frankestein gun. Handloads consisted of 55gr Nosler Ballistic Tips in mixed range brass over 27.5gr of CFE 223 and a WSR primer, and 69gr Sierra Matchkings in new Lake City brass over 25.5gr of CFE 223 and a WSR primer. Today gave nice conditions of about 60 degrees with a steady 10MPH wind directly from behind shifting to a slight left to right.

Not my best day of shooting, and 10 shot groups are a real bastard to concentrate hard enough on to pull off.
I initially sighted in with the M855 and shot my first group with it. I must have gotten a bunch of the worst lot of M855 I've ever seen, it won't shoot well in any of the three barrels I've tried it in. The first 5-6 rounds will do well, and then it gives the most random fliers, and settles back in. Not just in this rifle but in my other two as well. Frustrating.
Next up was Wolf 55gr that I ran mostly to test cycling with anemic ammo (passed with flying colors), which shot to the left quite a bit and I had to make a sight adjustment to get the rest of the group on my target... not great but it outshot the M855 in total group size including what got left on the cardboard. The M855 does have a tighter cluster aside from strange fliers.
I then ran my 55gr Nosler load, which also wanted to print to the left, with the first shot clipping the paper, at which point I dialed further to the right to get on the paper and ran the other 9 rounds. This load consistently shoots like the photo shows, which is not bad for being unsorted range pick up brass, plus I don't have Molon's chops shooting from the bench. I will run this load in virgin brass and re-test it since I think it has more potential.
My last test load before the sun dipped behind the Black Hills was my 69gr Matchking load. The first shot looked and felt good as it broke, and was 1" to the left of the bull. I couldn't resist the temptation to make another sight adjustment, and then ran another 19 rounds on top of my bull. There was a magazine change in there that I suspect interrupted the rifle's first natural point of aim off the bench rest. Like I said, I'm not a great bench rest shooter. Either way I will not complain about the results, this barrel and that ammo are capable of far better shooting than I am. I suspect a really skilled bench rest shooter, using a two stage trigger with a crisper trigger break could stack 20 rounds into a ragged hole. I'm just not the right guy, but I'm working on it.
I still have yet to test a hand load of 55gr Hornady FMJ, and 77gr Matchkings. I ran out of light today.
