While surfing the net rel to cans this evening--I came across silencershop.com. Good reading and a easy way to obtain a silencer. Also, under the "Services" tab, you can purchase a NFA trust for $130. You buy it, receive it online, and then fill out some questions on line. Go to the site to see the details. I already had a revocable trust so did not need the service but thought some of you folks might be interested.
