Faxon Firearms sought to create an ultra-lightweight, yet durable AR-15. After months of development and thousands of rounds of testing we’re proud to showcase the FX-5500. Coming in at 4.95 lbs., the FX5500 features our 14.5" Pencil Barrel with a permanently attached Slim 3-Port Muzzle Brake which meets the NFA 16" minimum barrel length requirement, 13” Streamline Carbon Fiber Handguard, and Lightweight Bolt Carrier Group.
