    I am replacing some internals on a G&P M870 (those plastic plunger tube 'feet' who like to break) and I have a tiny aluminum cap/spring (first photo below) and I cannot for the life of me find an exploded diagram online or locate its exact placement. Any ideas on where to find one?

    Help!

    So, over a week of crickets on here, I looked over the cast internals for any spot this little guy might live. So... I think this little 'piston' of sorts sits just above the rubber flap at the start of the barrel... which has a threaded bolt that holds it in and the small spring pushes against.

    Sound plausible, oh experts of the airsoft realm?

    Honestly, not many have opened to tinker with those 870's.
