This is my CQBR Block II-inspired build. It began life as an all-black 2014 Daniel Defense DDMK18 factory SBR. Then I caught the MK18/CQBR SOPMOD bug. Here’s the build list:

Optics:
EOTech 553 SU-231/PEQ holographic weapon sight
Knight’s Armament legacy front folding sight (taupe)
Knight’s Armament legacy rear folding sight (300m)

Upper (custom):
Daniel Defense mil-spec upper receiver
Daniel Defense mil-spec barrel (.072 gas port, not the .081 commercial size)
Daniel Defense MK12 gas block
Surefire SF3P suppressor ready 3-prong flash hider
TangoDown VFG
PRI M-84 Gas Buster CH with Combat Latch

Lower:
OEM Daniel Defense DDM4
Geissele SSA trigger
Colt mil-spec trigger guard
Colt A2 pistol grip
Colt magazine release
Colt H2 buffer
Colt carbine buffer spring
Colt rear end plate
Colt castle nut
LMT Gen 1 SOPMOD Enhanced Buttstock

Scott, thanks for the detailed build list!

    You think 10 inch barrels will become the standard some day? There was a time when the m4 was seen as just a sf gun and second line troops.

    • Bobing

      Until ammo drastically changes somehow, I hope not.
      Even if you make short-barrel-optimized loadings, you’re still missing out on a lot of velocity and range lost with a short barrel.

      • Esh325

        Don’t you loose a lot of velocity by going from a 20 inch barrel to a 14.5 inch barrel ?

      • CommonSense23

        Their are loads that are specifically designed for 10 inch barrels, and they have excellent terminal effects at range. I have seen guys throw 10 powers on 10 inches and have consistent hits out to 600 yards with 77grain.

    • Sianmink

      Well you don’t get much of anything for going longer than 10″ with .300 AAC BLK.

      • CommonSense23

        Depends on the load, you use supersonic, 12″ starts looking like a sweet spot.

    • Anonymoose

      I still prefer a 20…

  • USMC03Vet

    What is that sticker on the mag well?

    • TheNotoriousIUD

      “Objects may be closer than they appear”

    • Scott_AZ

      USMC03Vet, it’s a QR code label containing the Cage code and serial # details. Mine’s just a nice replica of what’s actually used in the military for inventory control. An arfcom forum member had these printed up for many of us as sort of a “final touch” for cloning purposes.

        I don’t know of anyone who actually uses those labels. Be interested to know if anybody does.

          Standard sticker on new weapons and those that have had a recent visit to Anniston.
          Most unit armories use a computer controlled scanner, inventory control software for cyclic service and issue/return hand receipt purposes.
          Some have tried to get scanning okayed for serial number inventory, but, at least until a year ago, inventory had to be a ‘hands on and eyes read’ process.

  • Sianmink

    Are there really people who are ok with the A2 pistol grip? Cause I’m sure not.

    • Scott_AZ

      Ha! There are definitely better AR grips out there – I’ve had a few of them. In this case, I went with the Colt A2 to be true-to-spec and I actually find it very comfortable. Now if I could just get it to fit more flush against the lower.

  • Kivaari

    Nice carbine.

  • no disrespect but have you even fired that thing one time?

    • Scott_AZ

      Solomon, none taken. It’s a fair question. I had put only about 400 rounds through it before I basically started over and replaced the upper with a custom build from Daniel Defense + the new trigger and other accessories. Literally just finished the build a few weeks ago and will be taking it out to dial it in.

      • Kelly Jackson

        Bro do you even operate?

        • Scott_AZ

          I operate operationally and stuff.
