Finally got my 5.56 sbr upper "done"
Primarily it's 300blk but figured I'd try a 12.5 5.56 on it. Haven't shot the new upper and still playing with placement of the microprism.

Lower Recap:
JSE/Zev matched upper and lower (SBR lower)
Larue trigger
SOLGW LPK
Magpul furniture

Blackout Upper:
JSE/Zev upper (matched to lower)
Rosco 8.2" 300blk barrel
Midwest Industries Handguard
Primary Arms Slx Gen2 Microprism
Radian Raptor SD CH
White Oak Armament BCG
Surefire M640DF w Pressure Pad
Silencerco Single Port ASR Muzzle Brake
Silencerco Omega 36M (shown in long configuration below)
I hate the look of the AFG but it does help a ton with it being so short

5.56 Upper:
Aero upper
Rosco/Sage Dynamics K9 12.5 (patrol length gas)
Forward Control Handguard
Burris Mtac 1-4
Radian Raptor SD CH
Expo Arms (Microbest) BCG
Silencerco ASR brake (gonna get swapped with an ASR FH)

Will be interested in results on the K9 barrel. They're supposed to be reasonably accurate, soft shooting and love being suppressed. We shall see.
