FN, Fal rifles Armorer's course from AGI, This is 2 hr long, all encompassing, more than any YouTube blerb,  it's in VHS and it's plays really well, made in 1995, find a good working VHS player, might have to adjust the display to "Standard" because of the format is old, Will combine shipping, FN's are no longer sold in my state (ilinois),
