• MATERIAL The FX-9 is machined from billet material, anodized type III aluminum components. Steel components are full hard nitride and black nitrided including the barrel, bolt, ejector, last round hold open, feed ramp and extractor for extended wear properties and corrosion resistance.
• WARRANTY Limited Lifetime Warranty
  Using aluminum casing, remanufactured, reloads or lead projectiles could void your warranty. Also, It does not include cosmetics, or issues that may result in changing out the fire control, buffer, buffer spring, or normal wear parts (ex. firing pin spring).
• IMPORTANT Operation
  The FX-9 Pistol is designed for right handed use. We advise left handed shooters to consider this before purchase, as some features may not be well suited to all left handed shooters.
  Trigger
  We do not recommend using aftermarket lighter weight triggers, if you wish to try an aftermarket trigger group we recommend keeping your factory supplied trigger group nearby for re-installation as it has more disconnector engagement built into it than a normal mil spec trigger group or after market trigger group.
  Buffer Tube
  The 16″ and 18″ FX-9 carbine come standard with a mil-spec buffer tube. The buffer tube that comes on the 4″, 8″ and 10″ pistol is proprietary to the KAK Shockwave Blade brace. All FX-9 models lower receivers are threaded to receive mil-spec buffer tubes.
  Upper
  A JP Enterprise silent buffer system will damage the FX-9 upper.
