No one will ship it to NY to avoid anyone putting it on a post ban gun and trying to hold the company liable, your M1 Carbine is a preban rifle, I also have a Universal, it was a 70s reproduction, that too is a preban rifle, to my knowledge you cannot buy an M1 Carbine made after '94 because they stopped making them in the late 70s.Okay, not to hi-jack this thread but in the same vein, different rifle. I've got a 1942 GI M1 carbine with the standard full stock. using the information above, I can put a folding stock on it correct? this would be a current manufacture aftermarket repro folder If so, how come no one will ship a folding stock to NYS?
As for the OP, any rifle with a date stamp on the receiver is exempt from all the stupid AWB laws, with ARs it is the date on the lower assembly, keep in mind that some rifles have an import serial number on them on top of the manufacture date, if the rifle was made in the 80s but imported and made into a "US" rifle AFTER '94, it is not preban, this is usually the case with AK47 clones like the WASRs.
So both of you guys have American manufactured (which means no import date worries) pre-1994 rifles, you guys can put whatever the heck you want on them. Keep in mind that a magazine for either rifle is considered a totally separate part and that owning a post ban magazine with a higher capacity of more then 10 rounds is a totally different issue and a different crime, the "high capacity" magazine law has nothing to do with the manufacture date of the rifle it is used in, keep that in mind.
