I've got some M1 carbine mags that I'm putting up for sale -- I will try to answer any and all questions that you have about them.
All the mags are pre-ban but still brand new, never used. None of them are still in their original wrappers.
USGI 15rd M1 carbine mags --- $9ea plus actual shipping (USPS Priority Mail)
These all have various USGI manuf. markings/stamps on them. I don't recall all the different letter codes but I will look for certain ones if that's what you want. I have about 50 of these available
30rd M1 Carbine magazines --- $20ea plus actual shipping (USPS Priority Mail)
I don't want to say USGI incase I'm wrong on these BUT they are most all stamped with "AYP" --- a couple are stamped with a "J". Under Fulton Armory FAQ list -- AYP and J are listed as unknown makers.
