My PSA BCG is stamped RG on the carrier. Its worked fine so far.
There are also BCGs that are GTG but with carriers that are unmarked, or the proof marked ground off. This is the case when a company gets their BCG's from another manufacturer. For example, I have an older M16 BCG that was made by FN, and the markings were ground off.
i have a delton hp/mpi tested m16 carrier. looked over the bolt carrier and couldnt find any markings that stood out but found a very faint "MP" on the bolt assembly. ill post pics once my dang phone gets charged up

FN carriers (at least those I have seen) are marked with an F. The bolts are marked MP F with an underscore under the F. DPMS carriers are marked with a D or two small dots.
