Faxon Sentinel FX8616 | 8.6 Blackout 16″

The Faxon Sentinel FX8616 is a purpose-built modern sporting rifle chambered in 8.6 Blackout with a 16″ threaded barrel and a host of match-oriented components. It ships on an MDT LSS Gen2 chassis with a B5 precision adjustable stock, G3 aluminum M-LOK handguard and a Rise Armament trigger; the barrel is finished and fitted with a three-port muzzle brake. For an optic under $1,000 that pairs well with this platform, consider the Vortex Viper PST Gen II 1-6×24 for close-to-medium range precision and rapid target acquisition.

This rifle is appropriate for precision target work and field hunting where the 8.6 Blackout cartridge and heavy-profile barrel provide a balance of controllable recoil and terminal performance. It is configured as a modern sporting rifle and is suited to experienced shooters who value a purpose-built, component-level assembly.
