AR-10 build inquiry

[Paperpounder]

Since I can no longer build .223/5.56 ARs I decided it was time for the 6920 to get a big brother in .308 / 7.62x51.

So far my list goes like this:

-Match set SI Defense Upper/Lower
-CMMG LPK
-DPMS SASS 308 barrel 18" (7.62.51)
-SI Defense NiB BCG
- Precision Armament M11 Severe Duty Muzzle break
-Troy TRX 15" battle rail
-Magpul PRS stock
- Charging Handle BCM gunfighter Large

Optic: Vortex Viper PST 6-24x50

I have never built an AR of any sort so let me know if I am on the right track here or if I missed a required part above. Or even of they are all compatible.

Build away sounds like it will be a nice piece !
