Is it side charging?

No it would have to be drilled and tapped. If it was chopped for a solo you could probably get it pretty light.

I think packgoatguy got his magnesium down to 4.1oz!

Yeah, you could chase weight down further than a 7075 upper, but for me, at 2# 11 oz or so for a fully functional rifle with a 7075 upper, I've gone about as far as I've wanted to go. I'm not sure I want anything lighter than that - at this time anyway - I suppose that could change!

The DS Arms bolt carrier is really nice, I use one in my gasser, but I'm not sure they have enough material in the area that would have to drilled and tapped to be strong enough (or as strong as I'd like, anyway). When I talked with them about that, they didn't think so...but they might be incorrect! It would be really interesting to see how it works for you.

Someone mentioned having the screws go all the way through the bolt, with a recessed hole thereby sitting flush. I wonder if small titanium screws would be an option for going down a size to compromise the bolts strength less?

I’m using it in a gas gun also. Just thought it might be a way for the guys running solos to shed a little weight. Looks like it could be done if set up like a BCA handle except fabricated aluminum handle with 2 smaller Ti screws. How long it would hold up though idk.

I just got my Shaw barrel. Looks very nice. I mocked up a rifle with the parts I had (still waiting on a few things).
Initial thought is that the light weight and trim handguard feel very different than a normal AR. I think I'm going to like it. With a suppressor it balances nice.

One question the NFA hammer pin won't go all the way through the lower on the right side. Am I missing something?

Does the hammer pin go through the lower holes without the hammer? If so, you may just not be aligned correctly. If not, well obviously a lower issue.
