I got this new post sample Galil ARM machine gun a few weeks ago from a place that was giving up their FFL/SOT
It's a reweld from a parts kit. I was excited when I got it. I took it apart to look it over and lube it up. I took it to the range with a few different brands of 5.56 to see if it was ammo picky or not. I loaded 20 rounds a fired a few semi auto shots. Then went to full auto and it shot good. Loaded up another brand of ammo, it fired one shot and then wouldn't chamber the next one, so I though that it just didn't like that ammo so I loaded up another brand of ammo and got it to chamber after a few tries. At that point I had forgotten to put back on my glasses. I fired the gun and immediately got a face full of gasses and other crap. I was lucky that the gun directed most of the gasses and crap down through the mag and didn't blow all of it into my face. The mag didn't fair to good.
After the initial shock of what just happened I tried to open the bolt to see what happened but I couldn't because the bolt came out of it's track and wouldn't move at all.
Also the safety had come out and the pins for the hammer and trigger had come loose too and where close to falling out. The tube that the piston goes in broke the ears off that slide in the groove in the receiver so I have to get another one of those. The top cover got a little bent, but I think I massage it back into shape again. I tried to get the bolt carrier to move with a hammer but it wouldn't move at all. I put the gun aside for a few days to try and figure out what to do and ask some people what their solution was. They said that a hammer need to be use to get it to move. I was trying to be gentle so I didn't brake anything. I tired again whit the hammer that I had been using and it still didn't work. So I went and got a bigger hammer and that started to work, I guess being gentle wasn't the way. I finally got the bolt carrier out and the bolt was left stuck in the gun.
I had to take a hammer and punch to get the bolt to rotate to unlock it to remove it. here is what I found when I got it out.
So it looks like the ass end of the casing blew out the back. After a little investigating I found out that the barrel was obstructed. The 21st shot, the bullet didn't exit the barrel. So the 22nd shot the bullet couldn't go out the barrel and the gasses didn't have anywhere to but out the back of the gun and into my face and out the mag. So now I have to find a broken case extractor to get the brass case out and figure out the best way to get the bullets out of the barrel. Do I pound them out from the barrel end or do I start from he chamber end? i have heard the machine guns are fun and if you have enough of them one or more is always in a constant state of being broken and being fixed. I have found out that is true.
