The FN M249S PARA (FN part no. 46100171) is a semi-automatic rifle chambered in 5.56x45mm NATO, built as the civilian-legal version of the compact PARA variant that FN America designed for airborne and close-quarters use. This black-finished PARA pairs an 18.5-inch barrel with a telescoping adjustable stock that shortens the rifle’s footprint for tighter spaces, while retaining the dual-feed system that runs from either a detachable box magazine or a 200-round disintegrating belt. It is built for collectors and shooters who want the compact PARA heritage of the M249 platform without giving up semi-automatic-only reliability. Few rifles turn heads at the range the way this one does.
