After searching on the internet for the perfect BCG, I ordered a Toolcraft nitrided BCG from Arm or Ally. I ordered it with the C158 bolt, but the 9130 bolt is $5 cheaper. It was $88.95 with s&h, with a cheaper option for USPS standard. It was listed as including a mil-spec o-ring as well.
Immediately I took it out it’s bubble wrap package and the bolt is clearly marked C-158.
The whole BCG is nearly devoid of tool marks minus some barely noticeable ones on the gas key. Speaking of the gas key, it is properly staked.
Disassembling the bolt reveals a proper black insert, spring and aforementioned O-ring.
Minus the cotter pin and firing pin, it has a uniform nitrided finish, including the extractor. Can’t wait to see how it works when I finish getting my AR-15 together.
