G'Day Fella's,

Gaff, yes both ends are TIG fusion welded in place, by me!
I achieve this, on a rotary jig I designed and made myself.

These suppressors/"Cans" are like most Military & Police marketed (but equally at home, on a Hunters rifle), suppressors these days.
With all of the "Can" being constructed of marine grade stainless steel, you don't need inquisitive or bored owners pulling these apart, to "See How They Work" and not re-assemble them correctly!!!

Gaff, I'm a firm believer in a couple of old engineering principles, they are;
1) Form Follows Function!
2) Keep It Simple Stupid! (The K.I.S.S. principle)

Merry Christmas
Homer
