This shotty is from the recently imported batch. A buddy of my with an S12, is now reporting a similar problem. This does not reflect well on izhmash.

It is more of an illustration for why Izmash is going bankrupt.

Got the bolt head separated from the bolt with a brass punch and a small hammer. Took a bit of force. Found a massive burr, on the rear edge of the retaining pin channel. The burr prevented rotation of the bolt, and caused the very rough cycling. I took the burr out with a small file, polished the inside and outside, now the action is very smooth. I am very disappointed by this, the shotgun barely has 50 rounds through it, and it has never been abused by me. The action was somewhat stiff at first, and got progressively worse. This burr must have been there to start with, and should have be

I can see the opening, and the pin is intact. I will try to force the bolt head out tonight.

Thank you for the replies and pictures, exactly what I needed. The pin is about 1/4 inch and it came out all the way. The pin channel is clear. I can get the firing pin to protrude from the bolt head, by pushing it. The bolt head requires considerable force to rotate, and it will only come out of the bolt to the very start of the retaining pin channel. What to do next? Force the bolt head out or not? What can be the cause of this? Bad spring? Metal chips?

Hi Folks I have a question regarding the disassembly of the S20 bolt. I have drifted out both pins in the bolt, I was able to remove the extractor, but I can't remove either the firing pin or the bolt head. The bolt head on weapon is very difficult to rotate and I am unable to pull it from the bolt. I do not want to apply too much force, is there some trick to this? I have a very difficult time opening the action, and I suspect there is a burr on either the bolt, or the bolt head, that is why I want to completely take the assembly apart.

I will take them.
