Firing pin difference Toolcraft and DPMS

[Albroswift]

After working on another members bolt, tried to use what I believe to be a DPMS firing pin in it, didn't fit.

Firing pin out of my Toolcraft did.

BUT...  DPMS firing pin fit my Toolcraft,  so, I've been running a small tip pin in a big hole bolt until now.

So I  believe a small dia pin came in the Toolcraft NiB BCG, new, out of the box. Never looked that close before.

I’ll have to measure mine tomorrow, now. I picked up a Toolcraft BCG for mine, but not sure if it’s big or small. 
  I thought the small hole bolts were for 6.5 CM.

That's a good find, right there.
