Cleaning rod.

Yeah I hope he didn't disassemble the upper to get the round out when a cleaning rod would have cleared it in about :02.

With a mallet?

If you can get a pair if needle nose vise grip or duckbill pliers on the case rim try TWISTING the round. I have broken stuck rounds loose that way.

You already put oil down the barrel so if the case turns even just a little bit it will be enough for the oil to seep down between the case & chamber walls.

Just a word of warning when hammering on a cleaning rod to clear out a loaded round. A number of years ago a bench rest shooter had one go off with that technique and it killed his wife with the empty case IIRC. The bolt was out of the rifle and she was sitting behind it.

Had a stuck loaded round, reload with a brass case in an AR. Tried the cleaning rod and actually ended up with it stuck on the bullet and unable to get the rod out. So with the upper off and out of ideas I decided to handle it like a stuck case in a reloading die. Used a cordless drill and a very sharp drill bit to drill a hole at the back of the case through the primer. Poured out the powder then ran a tap into the case. With a bolt and some washers over the barrel extension just turned the bolt into the case and with about half a turn with a wrench the case came right out.

I used a cordless drill so I could run the bit at a very slow speed so I wouldn’t generate much heat. Had safety glasses on and stood to the side of the barrel so if it went off it wouldn’t strike me. Had the barrel in a vice to hold it. I know there was a risk to this but figured if I went slow I with the drill I would be OK.

Glad you got it out without any major problems. If it had been a brass cased cartridge I would have recommended putting the barrel in the freezer overnight or in some dry ice. The brass contracts more than steel and just about drops out. Another alternative if the barrel is threaded for a MB or flash suppressor is make an adapter for a zerk fitting and push it out using a grease gun. Edited to add even if the barrel isn't threaded one could make an adaptor and epoxy on the barrel and later heat it to remove it. I have a real problem with the proceedure of pounding it out with a cleaning rod, even if it usually works.

Same here...I didn't think about putting it in the freezer. Even though it was a steel case would have been worth a try before pounding on a live round

Wow - talk about a coincidence and I was just about to post a new thread. My fresh built AR with the same barrel as yours did the same thing! The barrel is the Daniels Defense 5.56 1/7 10.3" and the round(s) were American Eagle 223 Tactical.

For me, since it was a new build, I wanted to function test first so I chambered a round, pulled charging handle to extract - no joy. Pulled harder - same thing. Took me about 5 minutes of sweating bullets before getting the first round out.

Considered it a fluke and tried again, same deal. Chambered but then wouldnt eject and took about 3 minutes to get it out of rowing the charging handle.

Spoke to the guy who sold the gun to me who suggested that the barrel was tight and to fire the round. Did that, and the damn casing is stuck in the chamber. Luckily, its fired so I'm not worried but WTF....

Well, I haven't had a chance to get mine back together, but sounds like I need to give DD a call.

Update for you guys that were having DD barrel issues.

I got the rifle back together this weekend and ran about 100rds of PMC brass through it and it ran like a champ with no issues. I haven't tried anymore steel cases and not sure that I will.

If there is no firing pin to react to a hammer blow, there's no way to ignite the primer.

Another option for these stuck cases (that I have not tried) is a can of aerosol coolant from an electronics supplier, maybe even Radio Shack. Spray the case head to cool it well below zero to shrink the case. I would try this if I had a tight case!

Why spend extra money when you can turn a pc can of air upside down to achieve the same cooling?
