APX 2 Stamp inside my 2017 1X

[Blackthidot 0]

I pulled out the end plug to cut a few inches off my new 1X stick and I noticed a bunch of "102" stamps inside along with "APX2" I can't get a picture of this and I've scraped most of it off because there was a bit of red paint over the lettering. 

 

Does anyone have have any information on why that would be in there? I know 102 is the flex but why would it say APX 2? That stick has been out of production for what...4 or 5 years? There's clearly different shaft dimensions, especially in the hosel but is it the same composite?

I believe this was answered on here previously. I think it was just the stamp on the tooling - they didn’t update it at the factory so they were all stamped APX2.

As always sir, thanks!
