View Full Version : re heat treating my 1/2 done AK reciever?

So at the build we had I left after just heat treating holes where the FCG gets placed. Problem is I'm not sure I got it hot enough. I came a bit late in the day and with all that was going on I was on my own for this portion. I didn't get my holes glowing yellow/red though the inner most portion did glow slightly, but not to the extent that I've seen in online tutorials.

I also dipped it in the oil and then heated it up again and let it sit.

I have this fear in the back of my head that due to bad heat treating i'll blow my ruggedly good looking face up.

Can I re-heat treat somehow?

I've also read that we should heat treat the top rails too.

my ruggedly good looking face up.

This is funny since I have met you. Just Kidding, I'm not an expert but I don't think that you have to worry about it blowing up. Over time and plenty of rounds the pin holes could enlarge or become egg shaped.

YES IT CAN BE REDONE. The lower rail ejector MUST be HT but not the upper. You can test for hardness using a file.
