you have a bucketlist of awesome guns! I've been thinking about building a .45 AR one day and dropping in a binary trigger but I'd love to see the belt fed 9. I didnt even realize you could belt feed 9mm. Also siaga 12s are sweet. I'd be interested all of those but the AR9 would be my first choice because like I said I didn't even know you could do that, btw thanks for the resteem!
