In 2015, FN USA introduced a Military Collector product line - semiautomatic versions of their military contract small arms. These were the M4, M16, and - most interestingly - the M249 SAW. The SAW is a version of FN's Minimi light machine gun, developed in 1974 and adopted by the US in 1982. The semiauto version, designated M249S, is exactly the same as the military M249 but adapted to fire from a closed bolt in semiautomatic only, making it a non-NFA item like any other semiautomatic rifle. The semiauto conversion as done by essentially chopping off the back of the bolt carrier to act as a linear hammer, thus allowing the use of the original style of trigger mechanism. Since its introduction in 2016, FN USA has made more than 10,000 of these rifles, truly proving the depth of American collector interest in this sort of thing (much to the surprise of the Belgian FN administration...).
