Just an FYI, with the optics ready guns on the horizon, CZ did take feedback from first gen owners and changed the mag release going forward. It's no longer ambidextrous but it is swappable. They say it's a geometry change but I'm pretty sure it's more than that if you lose ambi. Anyway, thought anyone coming across this thread in the future would like to know this won't be an issue for the OR guns made in the US.
