I think that is the same case activated system they have been using for a couple years. I have a 2nd generate LNL-AP also (it's about 1.5 years old, but it DOES have the arm sticking out for the case feeder), and that looks like the same case activated drop system I have.

My press came with the rifle rotor. I first bought the pistol micrometer insert for the rifle rotor (which had been discontinued already), but had problems. Powder would work itself between the rotor and measure body and bind up. The measure sometimes wouldn't reset, and then not drop charges. I suspect this is the reason it was discontinued.

So I bought the pistol rotor, which works much better - no binding. I did not have to get a new case activated drop system, the same system works with either rotor.

I don't think 050073 is 'new', despite the description. I think it is the same one they have been selling for a couple years, and it works with both rotors.
