This is a JCB drop in auto sear. This is one of the hardest NFA pieces to get and they rarely come up for sale. This one is all steel, not aluminum. You can legally put this into nearly any AR15 style rifle and shoot full auto. This item is registered in KY on a form 4. The first transfer to your FFL/SOT will be paid on this end.
This was purchased from Neal Smith a few years ago by me. It runs 100%.
I will ship it to your FFL/SOT for $29,900. All NFA rules apply. You can contact me at rext269@aol.com or call me at 859-361-9444.
Thanks for looking,
