What I would do is break it down and sell it for parts.
Do not fire it without head spacing it and putting that barrel pin in.
Save the NDS receiver for a future build.
Don't give up on the AK building. Hell even the top builders here have a few AKs buried in the closet there gonna get too rebuilding some day.
I read where the AK was rated a 5 out of 10 on a degree of difficulty in building.
Take you money from that. Get another kit and do another build. You can do it. Dont give up.
