Because the position you take while performing the clearance looks like you're operating a mortar. Collapse your stock all the way, take a knee, put rearward pressure on the charging handle with one hand, and strike the butt of the stock onto the deck. I've seen it done successfully on carpeting and hard earth. I wouldn't do it on concrete with my own gun if I had the choice.Uh, for the FNG, where does the term mortaring come from?
One other possibility is that a spent casing got logged in between the bolt and gas tube - unlikely due to the space that it locked up at - but I figured I would toss that out.
I do like to try pushing the bolt back with a casing from the ejection port, just to see if that can help, but I would not use tools.

Thats where the bolt is stuck at, and it won't budge.

A man with a gun is a citizen. A man without a gun is a subject.
No help to offer, I agree with all above...
However, I'd point out that I prefer to think of the bolt as being stuck "half open"...
The reason I did not suggest "mortaring" it, is because I have seen people damage their muskets doing that. And because I am an armorer and have a shop to do it in, I would prefer disassembling so as to not cause more damage. YMMV.

I had the exact same problem, and did what was said above, just mortar it. it'll get it unstuck. hope that helps!

Ig,
I presume these were chrome lined chambers. Two questions: 1) Is this chroming difficult to remove when reaming, that is how much service do you get from a tool? 2) Do the resulting 556 chambers after reaming (in the raw 4140 or 4150) give any trouble? I.e. do they tend to stick/corrode etc., more that corresponding chromed 556 chambers in your experience?
Many thanks
Robert
Robert,
I believe that the best answer I can give is that I was able to ream at least 70 carbines with the first reamer. We then purchased another and I am using that as a chaser to prolong it's life.
Since I have done the reamings the frequency of malfunctions using the Prvi Partizan and Bulgarian Arsenal 5.56 SS109 ammo either greatly decreased or ceased all together. But, since there were still some issues I recommended that we use the ammo only for punching paper, in the 5.56 AK's, or in an emergency in the Bushmasters. We had to weigh the options available to us and reaming the chambers was the best option we had. M855 ammunition is not easy to get here and we had to reserve it for duty use only.
