Finally, after a serious amount of frustration, my lower receiver is complete and functions perfectly! I will still have to get it engraved and go through the NFA process before I order the SBR complete upper but after several learning mistakes this thing came out perfectly, thanks to all of you who gave me advice it sure helped out especially the vice grip roll pin install. Oddly enough the easiest thing on this build for me was the front take down pin install, I used my Kroger card (key chain) to hold it in place and it was simple,
anyway parts:
Stripped DPMS lower receiver
RRA lower receiver kit with 2-Stage National Match Trigger (same as my RRA Pro Government DEA rifle)
Magpul CTR collapsible butt stock
Magpul MOE pistol grip
Magpul Trigger guard
