Since I spied the suppressors/moderators, I have been researching them here in the states, $200 US dollars for the state permit (federal stamp), and $600-$1200 US for the can.
I have two mausers that I would equip, one in 7x57 (deer, & antelope) and one in 8x57 (elk & bear). That's more money than the rifles cost (damn!)
