I saw some posts about wanting a .70" firing pin if using a 6.5 Creedmoor.  My question is which BCG for the AR10 uses the .70" firing pin?  I believe I read that Aero Precision does, but I wanted to see if other companies do as well.

I'd like to know if Tool Craft and Aim's BCG for 308?

I'd also like for the BCG to be in that 18 oz weight.  I'm building a light AR10 using 2A Armament parts, so ounces matter.

JP Rifles BCG does

I have a Toolcraft BCG that I run in my PA10.

It weighs 17.7oz, the firing pin measures .077in.  

Let me know if there are any other dims.. you need.

Thanks,  I keep on reading if building a 6.5CM that the .70" firing pin is what I'd need for the additional pressure.
