How does the rear bolt attach?

I'm still pretty new to AR's, but the 2 screw holes for the detent ball arm/ gas key is where I bolted it strait onto. I'll try to post a pic when I'm home in a week. Very solid, pulls and pushes strait in line with the bcg

I forgot to mention that the aluminum spacer also keeps the bcg from rotating and avoiding full battery. I filed it to within 1 thou of the width of the solo detent arm. Without it it wouldn't go into full battery

That’s well thought out, and that the bolt carrier rides smoothly is a plus. I read the earlier posts about issues with larger cartridges in the Solo, I wonder if your design solves that problem. And plus, it is super light and minimalist.

Thanks, I should know pretty soon as I test sticky undersized brass and NAS3 cases in the new ackley chamber as hot reloads. If I made the grip part of it a lot longer I could strike it with my palm to extract, I mean, it would still be a lot faster than a muzzleloader.
Edit: make that *oversize brass (for the ackley chamber/crush fit)
