They do say that with the new bolt, it should fire fine even though the legs are broken. The last time I did that, it snapped the bolt into 2. But I assume this was from the older bolt from my 2011 AKMS.
Wondering does any of your gun hit the bolt buffer so hard that it lift the bolt buffer up and chipping it little by little? This is the part I am talking about

I had to stuff some sponge to prevent it from chipping too much.
Fortunately, the buffer itself is very cheap to replace so it's not that much of a biggie.
