The story that I read somewhere was that it was tested once but the recoil either damaged the station or it would have affected its orbit so they never tried it again.

There was also Polyus which was going to be an entire battle station designed to counter Reagan's SDI satellites[0], but it never made it into orbit. It had lasers, though.
