There's the crunch and the reason I have been and always will be against AT. They designed and discussed it with whoever in the HO a way in which they could protect themselves and keep their business's going without any chance of prosecution for selling S1 firearms to non FAC holders. I see no reason why any forum should not allow discussion about this or even in fact allow detailed descriptions on how to remove anti tamper. We shooters need to be looking after ourselves, just like the AMTA industry members are.
