Lower Parts:
- BAD adjustable pistol grip.
- Mil spec 7075 receiver extension with H buffer (Titanium QD endplate)
- CMMG LPK (Odin Works V2 mag release and Strike Industries Chrome extended takedown pins)
- Ruger 2 stage FCG
- Magpul STR (may swap for an ACS)

Upper Parts:
- Strike industries Ejection port door
- BCM Medium Latch CH
- Toolcraft/Cryptic coatings Nitride BCG with c158 bolt
- Larue 16" PredatAR barrel
- SLR micro gas block

The last picture was just some of the lowers I picked up "just in case."
