I am not that great with EM machines to start with but I have a very humbling problem with this pioneer project I picked up. I can’t get the lock down bar off. I thought it was just seized to the machine but it wiggles around on the receiver. The handle will slide freely but the bar will not come loose. Is it possible that the handle has broken loose from the receiver and therefore when I open it the receiver stays locked? If so how should I go about getting that lockdown bar off lol. I appreciate the help
