Heres a link showing the marking. See post #20.

Good Luck,

I used talcum powder to see if I could find a trace of the TN inside the hand guard. I used my IPhone's camera with full magnification after dusting with the talc. Nothing to be seen. My guess is that the hand guard might not be Trimble. I wish it was but the main stock clearly is. I thought I read somewhere that Trimble sometimes did not stamp the hand guards, but I have not been able to find that post or text.
