I decided to buy a can with my Trust and beat the 7/13 deadline before the rules change. I contacted Shooter's Outpost and they were pretty well cleaned out of 7.62 cans, and the guy said he's got a 2 week backlog of filings to do, so he didn't think I could beat the deadline even if he did have one in stock. Contacted the Silencer Shop in Tx, and bought one with a guarantee that I would get in under the wire. Says they have an exemption from the ATF to file the Form 3 and Form 4 simultaneously. Only downside is that I waited a day to order it, and the price jumped $37.
