Hey CarDoc - just read the description a little closer:
-"Gas key is machined out of bar stock"
-"Gas Key Hardened to USGI Specifications"
-"Tool Steel Extractor"
I would say all the info you want is there. And these BCGs are G2G. I have a few, and they all operate just like you'd expect. Granted, I'm not running them full-auto and trying to see if I can melt a gas tube or blow through a gas key... but the few I use experience normal shooting and perform (i.e. I can concentrate on more important things - like making sure some redneck doesn't flag my whole family as they roll the dice on a barrel first inspection of a "maybe" cleared chamber).

Bcg with the logo at the same price. http://palmettostatearmory.com/index.php/catalog/product/view/id/2321/category/4459/...
How is this one different from their Freedom BCG? Specs look the same O.o
Does anyone know the material of the carrier?
I think they're always 8620. Bolts are generally 158 or 9310.
Great deal if this is really HP/MP tested.
Does anyone know if these have the mil spec machined gas key and extractor or if they are cast/MIM?
