Bought a Form 1'd lower from him on the condition that I be added to his trust to take ownership and possession of the item and use it, until he could have it released from the ATF NFA registry and I could complete my own Form 1. That was 5 months ago and he has yet to provide PROOF that he has sent anything to the ATF to pull this lower from the registry. The ATF also has no information on receiving anything from him. I've since removed myself from his trust and have put the receiver on a full length "rifle" upper where it is essentially being forced to stay, since I can't Form 1 it myself. If I knew what a headache this was going to be I wouldn't have bought it in the first place...
A fellow veteran (he was an officer so yeah, this is kinda typical behavior) and a local business owner should be as transparent as possible and you know... do what they say they are going to do, especially when given such a large amount of money for an item.
If I can assume he operates his "business" like he operates his personal online sales, needless to say I'll be telling people to stay away from Sean and pushing local training enthusiasts as far from Exoteric as I can.
