Slip on moderator for a 13.5 - 14.5mm barrel

[Shed tuner]

There is a universal fit that I used on my QB78.
Has two plastic rings that clamp down when tightened.
The was a pre owned one in Leicester airguns for £20.
I could pick it up tomorrow and post it on to
you.
There are Ok. Work better with some felt added.
I think sheffield air rifles stock them.

Thanks Neil... That sounds like the old webley pro-system.. they would work fine, but unfortunately are too heavy being steel.

Do you lnow if the one in question is steel or alloy please Neil ? If alloy, I'd defo like it please...

Thanks,
JB
