In stock right now at RedWolf Airsoft is the Cybergun FNX-45 Civilian Version Slide Conversion Kit which you can order for US$289.95... "This new set of Cybergun licensed civilian version FNX slides come in 2 versions, black and silver, both are constructed in steel and carries authentic 'FN' logo, 'FN Herstal' 'FNX-45' markings. They are designed to be direct replacements of the original slides with a more heavy and rigid steel slide. The slide set contains of the slide and black steel outer barrel.

At an affordable price tag, this provides an easy upgrade to your FNX to make it feel better, look better and more durable, the extra weight from steel construction also helps to enhance the recoil as the slide would now carry more momentum. Note this version does not have the battle plate nor threaded barrels, which would not be able to mount mini red dot sights but gives you a lower profile look."
