Hello All. I jsut recently bought 3 Colt 20rnders. Two of the floorplates say the following:
"Hartford Conn. U.S.A."
While the Other is stampled
The Mag bodies that have "Cal.5.56" are stamped with what looks to be a "U" with an "I" inside it while the mag body of the mag w/ the .233 has no stamp. Anyone have any info?
The ones stamped .223 are early Air Force issue mags from the 60's I believe.
the U I is for Universal Industries, they made them under contract for Colt
