I have an A-500 that hangs up when the bolt is pulled to the rear. If the trigger group is removed the bolt moves freely. I have put a new trigger group in the gun and it does the same thing. The gun is well worn to the degree that the receiver is cracked on both sides at the butt stock. I also noticed it has no buffer at the back of the bolt. What could make the bolt hang to the rear?
Does your gun have the carrier spring in the trigger group, or is it separate? The one I’m working on won’t allow the bolt to go back to battery without some assistance after you press the carrier latch. I bet if we solve one of these, we’ll solve both.

I know the gun needs to be retired but I want to find the problem first. I put a homemade buffer in and it does help the problem.
Thanks for your help,
Answer:
Ted It sounds as though the bolt has pounded the receiver in such a way as to allow the bolt carrier to sit canted when the pressure from the hammer is pushing it up. Inspect the rails where the bolt fits when it is all the way back, I suspect you will see it is disrupted here. The A-500 has a buffer while the A-5 does not.
