After 6-7 years sitting on my close, I finally got all the parts and got around to build it. The lower is an Anvil Arms, that I bought just before Barrack Osama was elected for the first time. Lower specs are:
Anvil Arms lower $99
BCM Buffer tube and spring $57.95
Noveske End Plate $20
LMT SopMod $125
Magpul Basic Grip with Bolt & Firing pin insert. $33
RRA LPK No firing group $60
LMT Trigger and Hammer Free
Stainless steel springs. (not necessary but for the hell of it) $14
Magpul Trigger Guard with a screw kit.(no pins to install) $15
Spikes tactical ST-T2 buffer $37.95

All I need now is, decide what upper I want to build. I have a 6.8 SPC barrel for my CQB so I might built a "hunting,precision" rifle.
