Well, it has been three years since I thought about doing these builds but with the elections on the way I finally decided to caugh up the money and buy the receivers I needed.

Firing Line has threaded receivers for Fixed stock AKs in stock but I was not really prepared for the new cost. They cost $700 EACH but these kits sure are pretty worthless without a receiver to mount them on so I ordered a pair of them to built the two Kbkg60 kits on.
Makes me wish I had purchased receivers a couple years ago but at least they are not banned and there was at least someone that was still making receivers fitting of these builds.
