The Faxon ION-X Hyperlite 5.56 pistol (brand part no. FX5510X) is a complete 10.5-inch AR pistol built to weigh 4.93 pounds without giving up duty-grade parts. Faxon Firearms pairs a pencil-profile 4150 CMV barrel with a carbon fiber M-LOK handguard and its patented adjustable gas block, so weight comes off the front end where handling feels it most. A Schmid-built Faxon Enhanced Match Trigger, an SB Tactical SBA3 brace and a Magpul 30-round magazine make it a finished gun right out of the box. It is built in Ohio for shooters who want a light carry-and-train pistol, or a suppressor host they can tune.

Key Specifications

• Chambering is 5.56 NATO, the standard cartridge for the platform with plentiful ammunition.
• The barrel is a 10.5-inch Duty Series pencil-profile 4150 CMV carbine-length barrel that saves weight while holding up to hard use.
• The barrel finish is salt bath nitride, which adds wear and corrosion resistance.
• Overall weight is 4.93 pounds, light enough to carry all day and fast to shoulder.
• The handguard is a 10-inch carbon fiber M-LOK Streamline, which cuts forward weight while giving accessory slots.
• The gas block is a patented adjustable .625-inch unit, which lets you tune cycling for different ammunition or a suppressor.
