I believe the Supersport piston seal will fit,but needs turning down slightly to fit the FWB cylinder.

a bsa seal does fit,after resizing a little,try here http://proteksupplies.co.uk/misc-parts.html

The supersport seal is 2mm too big from memory when i tried one on the cylinder of my 124, mine ran great on the maccarri mongoose seal already fitted, just tried the supersport seal to check fit. So I'd recommend the maccari,

V-mach do a piston seal for the fwb sport.

Quite handy on the looser tubed sports, but it will of course always need sizing. Macarri seals are good, but I had one sport where the tube was just too big for it (new seal) - fitting a sized BSA seal transformed the rife.

I bow to your experience there, but the bsa seal is a push fit into a recess & the fwb is screwed on through a central hole as far as i remember,so not as straightforward as fitting a direct replacement for the unexperienced.

Terry Robb used to offer seals for FWBs. Maybe he still does?

they are the same fitment mate... no mods required... FWB isn't screwed in.

My memory ain't what it used to be... in mitigation I have only had one to bits to check it did indeed have said maccarri kit in & that was over ten years ago...lol.

Length I think is similar enough that it will not be a problem.
