this is what is inside the awesome Weihrauch silencers...basically it's hair curlers cut to size, some felt damping material and 2 washers.
Going to put some in my empty HW100 silencer as soon as I find the right curlers
Now now Guido, each to his own!
The above filler was copied not to well by a local manufacturer, my AR78 blasted the bits out on the second shot, looks like Weihrauch got it right.
So Kobus how do they (the curlers) work? In your silencer I meen!
