Let's be honest, how many companies actually make their own BCGs? A couple? From what I've read, four companies make everyone's BCGs? As long as the carrier meets mil spec, the bolt is of paramount importance in these rifles.
Given this, I have a Brownells bcg, with their bolt and some toolcraft carriers with a monster bolt, and a black rifle company bolt. They all work well. The biggest thing to remember is the Brownell bolts are shorter so if you have to replace the firing pin, your have to use theirs. The others use a standard length bolt, so you can use any mil spec fitting pin.
