An authentic GI-vintage Carbine would probably never suffer the major malfunction suffered by my imitation, which was bought brand-new in late 2007.
It was built by Auto-Ordnance. If there had been an authentic carbine in the same shop, it would have sold for much less and been a much more reliable gun. My first gun purchase, and age 52.
The actions on the classic Carbines feel more rugged than on the weaker AO version.
