My Polish under folder "battlefield pick up" style. Gunbroker parts kit + Nodak receiver. I wanted the final finish to match the condition that the parts in the original parts kit came in.
In California we have to keep long guns at 30" minimum, which explains the long muzzle brake from Atlantic Arms where I also got the U.S. barrel. I still wanted to be able to fold down the butt stock.
What else I might do is put a slightly shorter compensator on and stick on a type of sling loop on the back in order to get the CA minimum 30 inches length in a different way other that using a 5" muzzle device. Tapco G2 trigger group, U.S. barrel, Nodak Spud receiver, U.S. 5" muzzle brake accounts for my U.S. parts count on this one.
I still need to go back and engrave the selector markings.
