The Romeo X models (the subject here) is not enclosed and commercially the enclosed M17 optic is still in the pre-release stage.
They have a history of offering other models in 6 MOA so it’s a bit early (and disingenuous) to be declaring they are “not interested” in making 6 MOA optics.
They are interested in making what ever institutions and individuals will buy.
I’m a fan of larger dots but Betamax was better than VHS and we know how that turned out.
