I remember as a kid my uncle had a Mossberg Sound Moderator made for a .22 rifle, I always wanted to own it but over time a gun tinkerer friend of his talked him into letting him try it out on a .22-250 he was building up for ground hogs. That once coveted item is now just a straight empty tube with no forward end or internals. I wish they would legalize them here, I have seen suppressed Ruger 1022's at the National Gun Day show in Louisville Kentucky and would love to own one. Back in more sensible times before the city moved to the country I used to shoot my AR15 back in a friends bush, try it today and within minutes there are police cruisers circling the block.
