I have a Little Bird for .22 in NFA jail right now since December. I might get to take possession of it in June.
Stupid.
Using a bolt rifle and sub-sonic ammo, all one hears is the click of the firing pin hitting the rim and the "clink" of the bullet hitting the steel. Absolutely zero muzzle noise.
A buddy just came back from Safari in Africa. The ones selling in the US for around a thousand bucks plus paying the gubberment a $200 tax to own it sells for around $150 in South Africa. Same brand.
When they got done, they tossed them into the trash as they could not bring them home. Buy suppressors across the counter everywhere but the US.
In Europe, it's considered to be rude of hunting or shooting without a suppressor. Some places, it's required.
