Product Description

The Faxon Firearms ION Ultralight complete upper receiver (FX5500-U) is engineered to deliver an exceptionally light, rugged AR-15 upper without sacrificing strength. It features Faxons pencil-profile 5.56 NATO barrel paired with an integral slim 3-port muzzle brake that brings the assembly to the NFA 16-inch minimum length requirement. A 13-inch Streamline carbon fiber M-LOK handguard helps keep weight down while providing modern accessory mounting, and the included Faxon Gunner Lightweight bolt carrier group and enhanced ambidextrous charging handle complete a fast-handling, ready-to-run upper.
