What is the best brand and source for a mil-spec Carpenter 158 phosphate 5.56 bolt by itself, not a complete BCG?
I did not post this in the where-to-get-it thread as I think it may entail more discussion.

SOLGW, BCM, Colt are solid choices. Between those three flip a quarter.
I’d probably pick up a few of these while they are on sale.

I don’t know about best, but for bolts only, some of the best options are more limited. IE: Sionics
I now see this isn’t C158 but 9310 so doesn’t fit your stated requirements.
Yep. I had one as a spare and used it in a more recent build. Not a lot of rounds down that particular barrel however.
If you are stuck with C158 I’d probably wait until these are in stock and maybe use one of those in the interim and toss it in your spares bin when you can find a good C158 in stock.
Pickings seem pretty slim for C158 bolts only, that are actually in stock. Good or bad quality.

I'll keep an eye on the SOLGW page. I am under the impression that C158/phosphate is a safer bet for "duty grade." I remember reading that the critical bores in nitride carriers are incorrect more often, presumably because they were manufactured with allowance for hard chrome (not applicable here but still a point of reference), and that 9310 bolts are more likely to have heat treatment issues than C158. I am open to the existence of a known-good nitride 9310 bolt.
Well, you could grab one from us.
