The Jager AP-15 and the later AP-74 were originally imported by EMF of California.
It was available in .22 LR and in .32ACP, and apparently a very few in .380ACP.
Later a "CAR-15" carbine version with a collapsing stock was offered.
Apparently there was also a wood stocked version known as the AP-75.
The design was changed slightly in later years, and the later versions used more plastic parts in the action.
The upper and lower receivers were made of "Zamak" zinc, with fairly thin plastic stocks and hand guards that tended to develop cracks.
The early rifles were close look-alikes to the original AR-15, right down to the triangular fore end.
Later rifles had the round "waffle" hand guards of the M16A2.
The early rifles, at least were excellent shooters.
Gun Parts Corporation sell all parts for the AP-15, AP-74, and AP-75.
