I'd like to first start with Hi.
Please pardon if this has been discussed, but while I tried, I could not locate a thread similar.
I have a Saiga 7.62, converted (with appropriate parts count) to use normal mags. I swapped the trigger out with a Danzig one.
Since doing this, I'd put around 225 rounds through it, maybe 300 rounds total. One jam (I think mis handled?)
Now to the nitty gritty. The image shows roughly where the crack is. It is cracked roughly 2/3 through (it is only thin stamped metal), and slightly bending downward (maybe 2 degrees). Try as I might, I can't get a good picture, but it is clear something is causing friction on it.
I know this is quite vague, and to be honest I'm half tempted to just ignore it (it being an AK...) BUT, an ounce of prevention and all that.
Note: the crack is ONLY on the interior stamped part (that looks like a bolt guide). The red line is the crack location.
