  • Plinker50 from USA asked:

    Will this upgrade the older model with the sliding breech cover?

    • Colin from USA asked:

      So, I recently got an older American Classic 1377 (it has the sliding breech cover) and it won't hold air when I pump. I can't seem to figure out what I need to do in terms of replacement parts in order to get this old lady back up and running. Any thoughts? Thanks in advance!

      • Robert from USA:

        First thing is strip it down and inspect all the seals and springs, and inspect all over the inside of the pumping tube for wear or damage. Replace parts as necessary, starting with o rings or seals. And of course don't forget the pellgun oil.

            You would have to check with Crosman, but I would imagine so.
