Perceptor's missile launcher's launching mechanism is most likely rendered inoperable. When the first Hasbro reissues came out a lot of people complained about the unsightly over-lengthed missiles, so Hasbro compensated with subsequent reissues by keeping the missiles the same length but making the launchers inoperable. Unfortunately with early reissue moulds Hasbro seems reluctant to modify them this way, hence why Pinkimus has those f'ugly missiles even though it's a relatively recent reissue.
