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:

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

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!

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

      @Solomon 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.
