Removing extractor pin on sig 556R?

[mizzi]

I don't post much, usually just search for answers... but I'm and it's stuck...

The tooth on the extractor is partially broken on my Sig 556R; too much steel case, I suppose.

I have the replacement in hand, but the retaining pin will not budge.

Any suggestions or advice is greatly appreciated?!

Looks like they may be flared at each end, and quite a pain to remove. Have you tried getting in contact with Sig?
