6.5 Grendel AR BCG - Milspec?

[gungate]

I have several .223 BCGs but only 1 6.5 Grendel (G). I want to pick up a spare BCG for my new BCA 6.5G upper. I am pretty sure BCA uses "type 2" BCGs. Can I get any brand T2 BCG for instance the below Aero Precision?

Also will a .223 firing pin work in a 6.5G BCG?

I would make sure of the type you have, call a vendor and make sure they are interchangeable within their own type and then check the head space of the new BCG with your upper. That's all I got.
