Update:
The 2K is on hold for now...
The Pre2k right feed STO is 90% finished. Currently has stock internals with a nelson spring kit from Straight Shot. Also has a Karnivor reg and Kaner Tactical barrel.
Waiting on my AKA Lightning Bolt to come in, stock bolt is pretty worn.
Sent a Kaner back to SSC to get bored and ordered some brass inserts from TY.
