    Where can I obtain a piston adapter for a synthetic seal? The lighter the better because the 55M has a very light weight piston and I'm trying to not go too heavy with the adapter.  Or does it really matter?

     

    Kind regards,

    Bill

    The weight won't be enough to make much difference whether it's aluminum, bronze or even Delrin. It's a pretty small part and the weight difference negligible. Piston seal fit would have a much bigger effect than added weight. 

    Any of the 25mm sized adapters should work. I believe Vortek sells them. 

    I made mine from Delrin and it works fine.

    Vortek makes the 25mm seal and adapter. If I remember correctly the Vortek seal is also a moly infused seal.

    A few years back I got a couple of these from JG Airguns, they worked very well.

    Kinda irrelevant to this thread but I have to mention that I was able to get an HW55 piston from JG Airguns. Having looked everywhere I was just thrilled to find it. I bought an HW55T  that looked good but when I shot it I was crestfallen that it just shot so poorly, roughly. Just not what you'd expect from a 55. Got it apart and found someone had replaced the original piston with something far more massive, longer and heavier. I've tried buttoning the piston, different springs but could not get it to shoot anywhere near as good as my other 55's. Probably some of that has to do with my lack of skill but I'm really happy to have another go at it with the correct piston.

    Best of luck with your 55T.  The original piston is very light (in a relative sense). Should make a huge difference.  You may want to check the air transfer port to make sure no one messed with that.  I think it's supposed to be 4mm.
