He just threaded the steel 90 and added an aftermarket bolt knob. You could probably lengthen the gas key portion and maybe not even have to cutout the upper much (but risk punching yourself in the face).

We talked about some ideas like this a couple of years ago, but none of us ended up going that direction.

Saw this yesterday and it looks like a good option for these types of builds, they even offer a grendel bolt face so maybe it extracts well.

There was something from the apparently now-defunct Atl opp shop (above) like this, and the Kali-Key. I think @Taudisio was even talking with his gunsmith about something like this (???).

This is kind of a simplified version of the Kali-Key idea, with the bolt handle moved forward to actually make cycling more ergonomic. If I could source the handle, I'd gladly make one on an upper with a dremel. He's using the same NBS upper here as the original Solos were using. I think the mod would be easy to do with a dremel.

The main issue I see is keeping it in battery with just friction. He's not really demonstrating any real field use as one might see in hunting.

Might we be able to combine the Solo's detent ball setup with this?
The funny solution is to just use an appropriately sized rubber band

I totally forgot about that project. He still has my cheap upper and bcg. We discussed it and he drew it up. It’s been a long time though and I’m sure it has slipped his mind too. I have him working on 2 other projects that I’d prefer to be done haha
