dan v:  I'd like to search old episodes, but you don't have a search function on your website.  Please consider adding one the next time you're tweaking your page.  Thanks. [We do now]joelfrederick:  I'm not sure if this is the best way to send feedback and a question.   That said, thank you for this episode.  I'd already discovered 80% Arms due to a comment you'd made and a friend that has nearly completed an 80% AR build.

I know you'd mentioned changes to ATF policy.  From what I understand I can build an 80% AR but after I die, this creates issues for my son who would end up with any guns.   If this is true, would a gun trust make this easier?

Ken:  I recently discovered your podcast, and want to listen to all of them.   I was able to down load to episode 90 using i-tunes.   I was able to download to 64 using  the webpage.   I want to listen to episodes 63 to 1. I really wanted to listen to the range bag segment, and that is where it stopped.  How do I get episodes 1 to 63?
