FN introduced the paratrooper folding-stock version of the FAL rifle in the early 1960s, and it became a very popular addition to their rifle line. Since the recoil spring on the standard pattern FAL runs down the length of the buttstock, fitting a side folding stock required a redesign to the internal parts, moving the recoil spring in front go the bolt, inside the top cover. For this reason, standard and paratrooper lower receivers, top covers, springs, and bolt carriers are not interchangeable. In addition to those changes, FN developed the folding charging handle for these rifles and shortened their barrels to approximately 17 3/8 inches. The standard muzzle brake was used, and the standard handguards and folding bipod also fitted. The rear sight was fixed, with just a single 250m aperture.
A batch of 1,375 of semiauto Para FAL rifles was imported into the US before the various bans on military style rifles were instituted, and this is one of them – an all-original FN made Para!
