Building SBR Honey Badger

[camoxjeep]

Just starting this build and wanted to get some opinions, I know their like @$$holes everyone has one. Good or bad what do you think. Going to be shooting 220gr subs.

Build is starting with BAD556-LW LIGHTWEIGHT 7075-T6 BILLET RECEIVER SET
8" Barrel 1/8 twist (dont have an name brand barrel just yet) pistol gas tube
Odin Works Adjustable Gas Block
Odin Works XMR 2 Extended Magazine Release (RED)
(Not sure on a BCG just yet) - any suggestions
Elf Service Trigger
MVD ARC Stock or Troy PDW stock or NEA CCS Stock (I like the MVD more as it uses your own BCG)
AXTS Raptor Charging Handle
Rainer Arms 45' safety switch RED
CAA UPG16 pistol grip
Building my own Titanium 308 can on a form 1
And going to SBR this on a form 1

Anyone got leads on melonite coated LPK minus trigger group?
Again not sure on BCG's, was thinking a lightweight BCG?
Anything else I'm missing?
