PAP M92

[686fan]

I recently purchased a PAP M92 AK pistol. I removed the thread protector & installed a Krink brake. The detent pin & spring went on fine, but I lost the tiny pin that goes in the tiny hole to retain the detent pin. I've been told that this won't be a problem; that the tiny pin isn't necessary.
Does anyone have any experience with this?
Thanks.
