Document 4: Ak 5: The first versions of the Ak 5 family were made by the Swedish company FFV Ordnance AB (now part of Saab Bofors Dynamics) under license from FN, with deliveries starting in 1986. This version of the Ak 5 is still in the inventory of the Swedish Armed Forces, but is no longer issued to soldiers, having been replaced by the Ak 5C and Ak 5D. This version uses fixed iron sights, and the Swedish Armed Forces have estimated that the maximum practical distance is 400 meters, but it can be used at longer ranges.

In 1964, Colt began selling its own version with an improved semi-automatic design known as the Colt AR - 15. After Colt's patents expired in 1977, an active marketplace emerged for other manufacturers to produce and sell their own semi-automatic AR - 15 style rifles. Some versions of the AR - 15 were classified as ``assault weapons ''and banned under the Federal Assault Weapons Ban.
