I recently ordered my Awesome LAPCO Ion MilSim body online and received today. There is a backpiece to it that comes off, but i wasn't sure if it was for easy bolt access or to fit a stock into it. There is no threading inside the back. It didn't come with a manual and the LAPCO website doesn't even mention this backpiece at all. I was hoping to fit a stock into it so if anyone could tell me if its possible and what kind of stock fits inside it would be greatly appreciated.
Sorry if there is already a thread for this, but thank you for helping.
