So the GI mag thread inspired me to go through my collection of GI mags.
While doing so I found for undated Adventure Line mags. Bought them used at a gunshow…
Am I correct in assuming that they are preban mags? All I have read state that they were only made in the 70’s.
Why would it matter?
Army and late Air Force contract mags made by Adventure Line Mfg. Co. made from 1966-1971. Floorplates stamped:
ADVENTURE LINE MFG. CO.
PARSONS. KS. U.S.A.
Eventually Adventure Line was bought by Center.
Because in some parts of the country, a post ban is a felony, and then there’s profit margin to consider when a person in a non-ban state is selling pre-ban mags to a ban state person.
It would matter cause I’d like to get them to someone in a ban state who could use them 
Nothing special to me, but if someone needs prebans they are special to them.
I’m in a ban state and can use them!
Necroposting something that is close to a year old, won’t help you.
We have a section dedicated to helping people locate items. I suggest you look there.
