Not the greatest pic, but here's what one of my lowers turned into:
Mk12 Mod0 (ish)
Anvil Arms matching upper and lower
Centurion Arms 18" SPR barrel
Ops Inc Muzzle Break
Troy BUIS
Nightforce NXS 2.5-10 Scope in Larue mount
Harris/Larue Bipod
Daniel Defense LPK
LMT Sopmod Stock
Magpul grip
BAD lever has been removed since this pic was taken
So I finally pulled my virgin 2008 Anvil lower out of my closet when the Black Friday deals started rolling out and put this together.
16" BCM middy standard upper group
Spikes BCG
Rainier Raptor charging handle & XTC comp
Ace skeleton stock
Rock River Arms Dominator2 rear sight
Daniel Defense Omega Rail & ladders
B.A.D. ambidextrous safety
Magpul BAD lever, XTM enhanced panels, and trigger guard
All that's left is the ambidextrous mag release I want, an Aimpoint or Eotech, and just maybe a Timney trigger from the gb if it happens. Might throw the four sevens light & switch I have on it as well. Overall, I'm pretty happy.
