They are normal. Apparently they parts were built years before the receiver was and were electropenciled like that.

That is a special alien code that turns the rifle into a ray gun, LOL Sorry had to toss that out there, I promise I am not picking on you. I am interested myself to add this info to the memory bank so to speak.

I had an exceptionally nice polytech and the bolt had electropenned numbers that did not match the serial number.

my poly has them as well but I cant seem to find any on my norinco

I own two heel stamped Poly Tech M14's as well. The numbers located under the stock on mine are as follows....

88 10 21

Which means my receiver was forged in January 88. My bolt also has the electro pencil numbers as well and I assume they are assembly numbers since they are different from my serial number, which on this rifle is 0057X. Perhaps our resident expert, Different will see this thread and chime in with a far better answer to your questions...

Thanks for the input guys,

As I mentioned earlier the trigger on this thing is excellent, far better than any of my long gone Springfield Armory M1A's

I was thinking since they all match they would be matched to the rifle, serial number is nowhere near those

if as was previously mentioned they were made prior to the reciever why would all 3 pieces match each other unless they were removed from another rifle,
dont they just pull parts from the parts bin, first in last out style?

Different? you out there?

3652 12 10 is your Date code like 7th Fleet stated. Pop back over to the thread you commented on where I was asking about this info and PM Different. He can explain it.
