Larue PST port selector

[SZ22]

I have a Larue PredatOBR 16 inch with about 3k rounds. I run it suppressed all the time. My PST port selector is seized in the suppressed setting. Doesn’t affect the cycling but erks me that I can’t get it freed up. Soaked it multiple time with Kroil oil with no success. Anyone have this issue and find a remedy for it?

I can't think of much to aid your issues.
Would a carbon cutting product maybe help ?

I would also e-mail LaRue... not to complain, but for advice to free up lever.
