Bolt

[244]

I'm really wanting to build ARs in .204 Ruger and a 6.5/LBC. I figure I may as well get a complete BCG at the same time, but I have some questions that I haven't been able to find the answers to.

I'm curious as to what steel is used in the bolt carrier and the bolt itself. I assume that these are not made by BHW, but that is only a guess.

Is the 5.56 bolt made of Carpenter 158 or (hopefully) 9310? Same question for the 6.5 which would benefit from the stronger 9310 due to the thinner skirt of the bolt face. 8620 for the carrier?

Are the 6.5 bolts the "standard" 7.62x39 Russian bolts (for headspace purposes) or do they follow the Alexander Arms pattern?

What kind of testing (batch/individual) must the bolts pass, like MPI/HP? Are they warrantied at all?

Thanks for any answers!

curious to hear the answer to this one as well, especially since I am still waiting on my bolt for my 6.5

I have a bhw barrel for a 300 rsaum I was wondering where do I find a bolt or a complete bcg to get this beast running?

Try DPMS. They made some several years ago, but have since discontinued that line. You might get lucky and find they have one laying around. You could also use a 308, .473 bolt and have it opened up, but you will still need to find an extractor.
