Hello. Not wishing to hijack Bleak23's thread, I will post my question here. Please bare in mind that I am in UK and not familiar with US laws. Please correct me if I have missed something. To legally own an FN FAL in the USA, it has to have a non original lower receiver ( restricted to semi auto only ) because the original would have been full auto capable. As the L1A1 pattern SLR was manufactured as a semi auto only and was never full auto capable, under US law, would it also have to have a non original lower receiver ? Thank you. Pete.
