Well my build is just about done (minus ATF approval on the MK9K).
This is basically how you turn a low end market PSA rifle into a $3,000 ninja machine. lol
Barrel should be coming in tomorrow and then the upper and parts are off to the gunsmith for a chop and re-thread. Then all that is left is optics.
For the record I keep a spreadsheet on all my firearms for insurance (fire / theft) purposes.
