I'm getting ready to order one for .22LR in .223.
I called on the phone the other day about them. He said send a check. He doesn't do credit cards.
I saw on his website about the 3 for $20 on the .22 mag to LR adapters. The only thing I can figure is that they must be very thin and damage easily which is why you get 3 for $20. That's not to say it's a bad product. If you have a question call and ask him. He seemed like a nice enough guy. When I got through to him on the phone it was 9PM eastern and that made it 5 PM there. When I talked to him he said he was working more than one job.
