    Raptor Rex help needed.

    I picked up a couple Raptor Rex regs from a parts bin at my local field. I have them broken down and have a few questions I hope more experienced members can answer.

    1.) Are the pistons the same as Mag pistons? I know the safety seals inside will need to be flipped, but I have a couple brand new mag pistons that I hope could be used instead.
    2.) Are these the same reg seats as a mag? If so, I have plenty of new ones.
    3.) Can I use a Buna Oring to seal the body halves as I am doing on Mag bodies right now?
    4.)One of the pins is bent. Is it acceptable to attempt to straighten it, or should I accept the L and just get one running?
    5.) Burst discs and bodies: I want to run the bodiea in the ultrasonic cleaner. Can I do that with the burst discs in place? aif I have to remove them, are the ruined? I assume they are red loctited in there.
    6.) Guages: I assume any modern 4500 guage will fit??
    7.) Cradles/Drops: Does anyone have 1 or two they would part with?

    Thanks!

      They’re not the same as mags, neither are the pins. Immortal Air makes new replacements though. It’s run by the old Air America people.
