I recently picked up several of their "PTAC 5.56 Full Auto Bolt Carrier Group with Charging Handle".

They look very nice, with good machining. The gas key staking is the best, most consistent I've ever seen. They look better than many factory BCG's I've owned.

There are no indications that they are MP tested, but they claim to use the right materials.

Of course it's impossible to tell if a component like this is truly quality until it's been thoroughly tested. It will be some time before I can vouch for that.

I'll take some photos when I have time.
