John,
.22 is a great caliber to silence and actually don't hear much more than sound of the toggle cycling. There are no restrictions on silencers here in Norway, and they have become a
very common sight these last 10 years. I use silencer on all my rifles, including such rifles as marlin 336 and the trusty old K98
The red-dot luger is now history and picked apart.
Much more interesting is the one with radium inserts! Very interesting set up.
