I went ahead and purchased the lower for my SBR build. Tax Stamp in progress... Build specs look to be the following:

Lower:

RA 45 degree forged lower
Geissele SD-E Trigger
BADASS Short Throw Safety
Minimalist stock
VLTOR A5 Buffer System
BAD EPS
LPK minus FCG
Odin or RA extended mag release
Possibly a Battery Assist Lever since my NTD lower won't fit one
Magpul K2 Grip
RA Trigger Guard

Upper:

I'm undecided. Either a Noveske 10.5 SB with a surefire flash hider or a BCM KMR Upper.


I've always wanted a Noveske upper, and I feel that since I have a suppressor in the waits, it will make more sense to go this route. This is definitely a part by part build, and more out of enjoyment of building than anything else, so I wouldn't mind putting the extra 700 or so in a noveske.
