Yes, mortaring is a trained technique. Always fully collapse your stock first if you're going to do it.

Yep, removing a stuck case. This. It's called mortaring. Much faster than shoving a cleaning rod down the bore and hitting it with a hammer.

Like others have said, mortaring. It is one of those anachronistic techniques that has been trained in the Army since the M16 was first adopted, and didn't change after the M4 replaced it. It wasn't a big deal for the M16, which had the solid buttstock, but you can break an M4 using that technique no problem if you do t wrong. You have to collapse the stock and hit it with the buffer tube side of it while pulling down on the charging handle, which generally means turning it upside down if you want to keep it downrange. If you don't, you will break the bottom part of the milspec stock off, I've seen it happen many times.
Post the vide so we can see it |

Works, fast and effective method to get back into the fight. I've only had to use once and that was when I was qualifying and had a round stick. Did it quick, fast, and in a hurry and still qualified expert.

Also known as "shocking" I have to mortar ARs on the line sometimes to clear stuck rounds(usually shitty reloads or Russian steel case), occasionally. Works 99% of the time. The look on the AR owner's face is always priceless.

It's usually with a bolt override failure where the case is stuck in such a way you can't rack the charging handle but you also can't open the lower/upper due to the bolt being partially backwards. The butt slamming causes the bolt to travel back a little and thus the case falls out naturally due to gravity.
In a firefight, I suppose you could slam the rifle onto the butt but an easier way to do is to use your middle finger - otherwise known as "finger banging" your rifle such that you push the bolt back and the stuck case falls out. Another option is to use a tool such as a spent case, magazine lips, anything that catches the side of the bcg, and simply move the bolt backwards. Or you can use this tool: https://www.leatherman.com/mut-29.html which allows for the hook to move the bolt back. |

I saw Mark Wahlberg do it in Lone Survivor.

When I haven't cleaned my 5.45 AR in a long time sometimes the bolt is stuck forward so I have to mortar it open before I start shooting.

Remember collapse the stock before any attempt to "mortar" the rifle. If you do not collapse the stock you will regret what might happen to your lower
Done correctly the technique works like a charm to remove a stuck round from the chamber.

Bent a lock pin on a CTR mortaring out a stuck case. I ended up making a new one out of stainless.

It's a method to apply inertial thrust to dislodge a stuck cartridge case.
If you've never seen it or done it, you might not be a veteran. |

You are supposed to collapse the stock fully before attempting this tactic. There should be no stress on the stock position locating pin. Quote HistoryQuoted:
