OK, here is the deal. When the BATFE decides what goes on their list of what is acceptable for a C&R firearm, why does date come into play? By definition, 50yrs or older is C&R, or whatever the BATFE has in their book. Now I think its AIM that has a group of CZ70's in stock. However they won't sell them as C&R because they were manufacture in the 1970's. But BATFE has CZ50/70 listed as C&R acceptable. I understand they aren't 50 years, but the model has been accepted as C&R. Why can't They sell them to us then, if it says it's OK? Also, Zastava is producing new runs of the Yugo M57. I understand it's brand new, however, This isn't the M57b, or is it just another reasonable facsimile of it? They market it as the M57, and as such, it should be C&R. Any help would be welcome. Thanks in advance.
