What does the brass look like when you get it out? I had a PSA barrel I got on clearance with a very rough chamber, dull cutter caused chatter, leading to major extraction issues. I ended up polishing the chamber with a fired case (coated in fine lapping compound) then a bore mop chucked in a drill (coated in flitz), problem solved.

Other than the occasional case rim ripped off from the extractor, the brass itself doesn't looked molested. But I am shooting suppressed so it's dirtier than normal. I will take a harder look at the brass and see what I can find.

Oh and damn, I wish I would have read the 25 page Ice Arms greatest hits thread. I bought this barrel mid last year from Colin, and put it away till my forms came back to build it. Wondering if I just got a piece of shit barrel, and should maybe start over with something else??

Are you using a adjustable gas block? Subsonics?

Carbine length gas tube, DD low profile gas block. No subs, it's a .223/5.56 build. It's gassed fine, as it cycles and tries to push a new round into chamber. It's just not extracting the spent round.

I would rent a 5.56 NATO chamber reamer, or stop by and see your friendly gunsmith and have the chamber finish reamed. At the very least, have the chamber checked for size. Being that the barrel is from ICE arms, there is no telling what you have.

This maybe helpful, if for nothing else than measuring shoulder pushback if you reload? My .02

Wasn't Ice arms one of the recent problem barrel manufacturers? I remember seeing one just recently where the barrel was all crooked. Was visually off to one side. Most complaints, as I recall, revolved around accuracy but I have read some extraction issues also.

This barrel has zero accuracy issues for the single shot capability it has right now. It just will not extract cases.

Well fuck me with a bad barrel. Just found this nugget on the Ice Arms greatest hits thread:
This is my experience with Colin and Ice Arms:
I purchased a 16" nitride barrel back in August to use with a Adams Piston system. Here is what my gunsmith Erik Winter, who works for Windham Weaponry found during assembly. "The first case I fired stuck in the chamber and ripped the rim off. The case looked really rough. I polished it and it had trouble chambering. Tried firing it and it ripped the rim off again. Polished it again and almost made it through 60 rounds before it ripped the rim off again". During disassembly, Erik noticed the gas port size is kind of large for a 16” barrel. Windham Weaponry uses .063” The port on this barrel is .076” I don’t know if this would have been an issue or not. The Adams Arms manual just says to use the lowest setting on the gas plug if the gas port is over sized. After contacting Colin, he acknowledged that a few barrels were sent out with out of spec chambers. The Barrel was sent back to Ice for a replacement......here is where the fun really begins. First, it took two months to get a replacement barrel. When the barrel arrived it was a mid length, not a carbine length. This was all it took for me to say F*ck it!, I want a complete refund on my barrel and bolt that I purchased from Ice. I sent an email to Ice requesting a return call tag and a refund. I received the return call tag on November 20th, but no sign of a refund. To anyone that does business with them, buyer beware, they are worse than Botach Tactical ever was! |

I know Ice Arms doesn't have the best rep, but if you're chambering and firing fine but ripping the occasional edge off the case and not extracting you have a timing issue. Typically this means you are overgassed and need to slow things down a bit by adding in some dwell time. What appears to be happening is your action is moving faster than the case is contracting. Here's the thing... you pull the trigger, it goes bang. The case swells in all directions and stops when it meets the walls of the chamber, crearing a seal to send all the gasses down the tube behind the projo. The system must have enough time built into it to allow the case to return to its original size and stop gripping the walls of the chamber. To do this you either need a longer gas tube to extend the time it takes for the gas to enter the carrier, or a heavier system (read heavier buffer and/or auto carrier) to slow the reaction of the carrier and allow the case time to return to its original size. The shorter your gas system is the more of a problem this can be. You have a short gas system and I will bet dollars to donuts this is your problem.

It's not ocassional, it's every round. Also, after cycling, even on cases that don't lose their rim to the extractor, the spent case cannot be cleared without a rod in the barrel and significant effort. This isn't a gas issue. Heavier buffers were the very first thing I tried. Then bolts, then ammo choices.

You could buy a reamer and ream the chamber to 5.56 (assuming it's not chrome lined).
ETA: I have polished a chamber with steel wool, wrapped around a chamber brush and chucked into a drill. It worked. It's obviously not ideal, but it made a barrel useable again after a russian steel (5.45x39) case was fired through a 5.56 barrel then left for a couple months. Chamber looked nasty, but cleaned up in about 5 minutes. |

Just an update. Said "Fuck it", and bought a new BCM barrel. Will send this current barrel to be looked at and reamed if needed. If it is usable, it will go on another build. Either way, probably done buying "new company" products, and will stay with the known performers from now on.

I've had impossibly stuck cases before when switching between steel and brass cased, but if that was the issue it shouldn't be happening every single time...just ideating here...

Just saw this thread. Always wanting to try new companies, I ordered from ICE last year while I was deployed. I didn't get eyes on the stuff until months after I got home. One order was screwed up, I emailed, and it was rectified within a few weeks. I felt good about that, and after using one of their bolts felt I could order from them again. I bought 1 .308 barrel, and 4 5.56 (1 middy, 2 carbine, 1 10.5). No issues wiith the .308. It shoots very well inf act. Still felt good. Finally used the first 5.56 barrel, one of the carbines. Ugh Ugh Ugh. Same issue! It had worked fine hand cycling dummy rounds. So I figured she was good to go. Took her out, same exact issue. I bought some Flex Hone stuff to polish up the chamber (400 grit and 800 grit). I plan to do just that this week before heading out to the range again next week. I need these to work. If I have almost $700 in barrels that are junk, I will be a very sad person.
I, like many, am done with ICE Arms, but I just want what I have to work. |

I hope the BCM barrel fixes the issue for you but I think your carrier was just moving too fast and slowing it down with full auto carriers and heavier buffers may have solved your problem. I had the same issue when I tried to build a 7.5" pistol. It's moving so fast it's just ripping the rim off instead of pulling the case out to eject it.

Thanks. I hope this solves it also. I had already tried different carriers (F/A and Semi) and ran through carbine/H1/H2 buffers. I did not try different springs, because at that point I didn't think it would make a difference. Gas port opening on the old barrel is 0.06 (according to micrometer).

Quoted:
Hey guys, hoping you can help. I have a build that I am having problems with. First one in many that I have experienced this, so I am at a loss for ideas. This build is using an Ice Arms 11.5" .223 barrel, bolt and carrier. Round is chambering fine using every type of ammo I have. Wolf steel, Wolf Gold, Remington green box, Older Hornady Tap, Winchester PDX, etc. Problem is I can't get any spent round extracted. I have tried 3 different known good bolts, and none of them will extract the spent case. Chamber problem? Any ideas? The issue is the barrel! I had the same issue and switched the ice arms barrel with a Daniel Defense barrel and everything was fine. The chamber is too snug in the ice arm barrels. When fired the brass expands due to the heat, and therefore causes failure to extract. What a horrible company. |

Very Nice! Glad to see you got it resolved & working.
Ice must have used a reamer well beyond it's life expectancy or they got sent a bum one. Either way, they should have been checked/tested before being shipped. |
