First and foremost, a huge thanks to all of the gurus on this board. Padom, bigjake, and many others who's knowledge base and willingness to share made a tremendous impact on purchasing decisions ultimately leading me to my goal - 1/2 MOA from a AR 10 framed build of my own.
I finally completed my load workup and fine tuning of my first AR10 framed rifle. I was looking for two things, consistency and sheer accuracy. The JP products are nothing short of superb. The build went together flawlessly. I had to work out some bugs with the rifle beating up brass pretty hard and again, thank you for everyone's input who commented. I have my gas block barely open and a heavy spring in the SCS. I also added one tungsten weight. Truly, when the last tungsten weight was added, the rifle recoils equivalent to a 223 and it shaved off 0.1-0.2" from my groups. I followed a recrnt thread that suggested fine tuning the gas system can improve accuracy. I agree 100%. I have noticed this with my experiments as well.
Below is the build list. The scopepictured is a Leupold 6.5- 20 with a tmoa reticle that I had available. This would be the only upgrade from here. I only have access to a 500-yard range at this time so it fits the bill fairly well. 38 grains of h4350 it's not what I was hoping for but I was really looking for accuracy over anything. Also, it is much more easy on the brass. I did find a Haier node up around 42 but it was knocking primers out of brand brass.
Build List:
-JP builder's set 6.5 CM +2 gas system with included bolt
-JP adjustable gas block
-JP lmos bcg
-JP tank brake
-JP SCS with heavy spring and tungsten wt.

Again, thank you to all of the knowledgeable folks on this board and helping me obtain my goal.
