I just got my m1a back from Springfield and I have a problem. Here's the issue. I lock the bolt back with the mag well empty, but when I pull the op-rod to release the bolt, it locks up and won't ride forward. I'm able to see that it's not getting caught by the bolt stop, so that's not the issue.
After jiggling the op-rod a little, it will release and ride forward. I'd be very grateful for any input and help. Thanks everyone.
