Then how do you explain the CZ 82 under C&R rules? Mine was made in 1987.
Remember that there are 3 different criteria for C&Rs
1) Any firearm 50 yrs or older in its original chambering. Gun could have a sight change or something minor but many major alterations remove the C&R exemption.
2) Any firearm on the approved C&R list found on the ATF website. Remember - this list is not all inclusive. Most C&Rs are NOT on this list.
3) Any firearm connected to a historic place or event. This would need to be proven, and so paperwork with the gun would be needed.
