The X-BOW FMA Supersonic was and still is a real revolution on the market of (pistol) crossbows, which cannot be made any better - actually... However, X-BOW fma Engineering did not want to rest on its laurels and took on the Supersonic again. The result is a reverse crossbow that is once again a real innovation: The X-BOW FMA Supersonic REV. A small, compact, if not THE smallest, reverse crossbow on the market.
