Haven't seen "A" stamped on a bolt carrier before. "TC" for ToolCraft on a very few. A few with "M" that may be for Microbest, don't know for sure. Most quality BCG's well have MPI on the bolt and the no other markings. I've looked at over a hundred BCG's and fewer than ten have any letter marking.
