| I have read several threads from various sites discussing this pin. Basically i have a casing that is very very stuck in the chamber. I have tried everything i have read to remove it and just cant get it out. There is a wooden dowel broken in front of the casing preventing me from punching it with a brass or steel rod. Long story short i have removed the barrel from the upper, and if i could just get the extension off, i might be able to get some vice grips on the casing to pull it out. I have read that the pin can be pulled out with some pliers, but also that it cant be removed at all, any must be drilled out. I have also read about when replacing the bbl extension that its very hard to get it aligned, but since the holes are already there, dont you just line up the holes and drive a new pin in? Im going to get a good pair of needle nose vice grips to try to get to the casing before i ruin the barrel, but if that doesnt work, what else can i try? I dont want to just torque the extension off, i have read it will probably mess up the barrel threads. |
| The whole spent casing is stuck in the chamber. I went and bought a brass rod to try to tap the whole thing out but its so stuck in there that the brass rod started to deform the wood and wedge it around the brass rodl in the barrel to the point that it was difficult (but possible) to remove the brass rod. I have tried soaking the chamber part of the casing in several different penetrating lubes and solvents to no avail. I really cant afford to take the barrel to a gunsmith and im not in any real hurry to get it fixed, but would like to get it running again eventually. I did purchase a broken shell extractor in case i do eventually end up ripping the end off. The casing is russian steel by the way. |

if you already have the barrel off, can't you drill a hole in the back of the casing then run a big screw part way into it, to give yourself something to grab onto or pry against? With the barrel off you could use a cap head screw and a washer as a spacer. Just like a stuck case extractor used in reloading. If the case is spent.

How about a Hydro-forming solution??
Buy a Bushmaster (or other brand) 4.5in or 5.5in long flash hider, attach to muzzle, tip barrel vertically in a bench vice, suspended off the bench by an 1/2inch ratchet socket. Fill barrel with water to top of flash hider. Use a 1/2" or 5/8" dia rod with a cushion taped to one end. Put on safety glasses and old work shirt. Place cushioned end just above top of water and use a hammer to swiftly drive rod into water filled flash hider. Pressure forces case out the other end...or maybe just the primer...but thankfully you have the entrance to the case blocked by the stuck wood... |
| After 2 months of stuggling with this thing i finally got it out! I think the torch was the trick. I heated the end of the casing up, and it still wouldnt budge. I then drilled the primer pocket out just larger than it was, then put a broken bolt extractor in the hole. Put some vice grips on the extractor and gave it a twist and what do you know? The casing twisted with it!!! I worked it a few times and it pulled right out. I think the torch broke down some of the polymer or whatever was holding it in there. |

Awsome!  Now put it back together and go shoot some BRASS ammo. Steel is for AKs
Here comes 100 people that never had a problem with steel........ What about those who have had the same problem with brass cases? I have never had this problem with a steel case, but have had it with brass cases. Granted I have always used an old sectional cleaning rod with great results.

I have never had this problem with a steel case, but have had it with brass cases. Granted I have always used an old sectional cleaning rod with great results. I've had problems with brass and steel stuck cases. The sectional METAL cleaning rod always gets it out with ease (though a hammer was necessary once on a BRASS case). |

Almost certainly it was the "whatever" holding the case stuck, and NOT anything to do with the coating on the case. First, experiments have demonstrated that the coatings used on steel cases do not melt, nor do they become sticky. Instead, they burn off. My theory about the "whatever" is that it was a combination of soot and unburnt powder that had collected in the chamber. Steel cases don't expand quite the same way as brass cases, so they tend to allow a little more gunk to collect in the chamber. Any ammo will cause gunk to collect, but steel cases are just a little better at it. If your "Russian steel-cased" ammo was Wolf black box, you can add "lower powered" to the mix and expect that the case mouth doesn't seal as well ad other steel so you get even more gunk built up...
I think the torch broke down some of the polymer or whatever was holding it in there. I haven't had a steel case get stuck, though I like Barnaul's ammo. I did have a brass case get stuck once though. It took a steel, sectional cleaning rod (actually a bunch of GI rod sections) and a combination of big-assed pliers to hold the end of the rod and a lot of hefty thwacks with a hammer to get it out. The issue? This was a 9mm round stuck in a carbine barrel, and the US-made ammo (Winchester USA brand) was, frankly, filthy. I knew the lower was getting dirty, but didn't think about how the chamber might be getting dirty... Oh, and blowback actions are inherently filthy anyway... |

The ammo that i got stuck was cheap russian steel from walmart, "tul ammo". I have seen tula in several different kinds of boxes. I attribute the casing getting stuck to the steel case and probably lack of good cleaning of the chamber.
After i got the casing out and most of the wood i could look through the barrel and see mostly light. There was still a tiny bit of wood stuck around the inside of the barrel. I couldnt get my cleaning cable down there so i rammed the brass rod down there to knock most of it out. I was able to get the cleaning cable in and pull a brush through a few times. I think its all clean now, but im worried about the gas port holes. When i look down the barrel i dont see any debris. Would firing the gun be safe if the gas block holes are blocked at all? I figure if the projectile can travel all the way out the barrel it will be okay but just wont cycle well, and hopefully blow any debris into the gas port then i can clean it out then. Its a piston driven gun so i can just take out the piston and clean that area out. |
