Are they both MPI and HPT tested, too? Doing an Aero Precision upgraded parts assembly and I like the Nickel Boron and Titanium nitride BCGs. Thank you.

Depends on who they made it for. They will make house brands to the buyer's spec, so those tests are going to be customer/contract requirements. You could always go with Aero Precision or BCM. Others you can't go wrong with are LMT, Lantac, Geissele, WMD, Colt, and Brownell's house brand. Not an all-inclusive list, but good choices. There's lot's of newer/flashier stuff, but my favorite of all I have are the RRA hard chromed. I don't know if those are still in production - haven't seen one in a while, but so easy to clean and will run & run & run. My Lantac is 2nd favorite just because I think the cam pin is cool looking
