Unfortunately I'm too poor to own either a RR or RDIAS (let alone both) so I'm hoping with one someone can answer a technical curiosity.

RR, of course has the GI sear and parts to go with it. The GI sear has the arm on it which allows the selector to cam it out of the way when not in use. Presumably, this means it doesn't move or make contact with the BCG during semi automatic fire.

RDIAS's trip possesses no such arm. It is completely unable to move out of the way with the selector set to semi. Wouldn't this mean that the trip is able to catch the hammer during semi auto fire as well as auto?
In other words, hammer falls, bcg moves rearward and recocks hammer. Hammer then catches on trip arm. Trip arm is tapped by BCG's forward movement, then hammer catches on the disconnector hook. Trigger released, hammer catches on trigger nose, cycle repeat.

Is that right or am I missing something?

Forgotten Weapons did a good video on the difference

OP: You are 100% correct in your functional assessment of the two sear types.
