via the charging handle & cycling the bolt?

The Hornady Rapid Rack is grabbed by the extractor and will pop out if you use the charging handle or use the device itself as a charging handle.

This is an interesting question and timing is everything. I shot my first 2 gun match just the other week and commented that I needed 3 hands to insert/remove the chamber flag while holding the bolt open, resting the butt on my hip and working the slide catch on a AR.

Our RO’s have a pretty good drill down where they can catch the ejected round with one hand while simultaneously inserting the chamber flag while the shooter holds the bolt open and holds the flag in place while the shooter slowly closes the bolt all in one fluid motion. It’s a thing of teamwork beauty when it works.

I definitely have this on my wish list at Midway.

Thanks for posting this.

Thanks, Rustpot. That's even better than I'd imagined.
