Cant remember who it was. Iether Sig’ or grumpy Walt mentioned that there’s no need for mor than three chambers but of differant volumes in a moderator so here’s one to try.
And yes i noticed it has four chambers.
I started dividing it with the miller instead or a pencil 😳 But there are three differant size chambers (at least i got that part right)




Took as much material away as i could to max the volume.
Would’ve liked it a inch or two longer (story of my life 😥 ) but al see how it goes.
YN, not forgot.
Later, Sean.

You know the one i mean…
The one that knows better than AirArms about tube design.
That man should be a millionair with what he knows.
Wonder why he ain’t.
