The Faxon Sentinel in 8.6 Blackout (MPN FX8616) is a precision AR-10 pattern rifle built around a Faxon AR-10 action and bolt carrier group, pairing a 16-inch threaded barrel with a 1:30-inch rate of twist and a 3-port muzzle brake. Faxon Firearms houses the action in an MDT LSS Gen2 chassis with a G3 aluminum M-LOK handguard and a top Picatinny rail, and fits a Rise Armament trigger, a B5 Systems Precision adjustable stock, a B5 pistol grip, and an ambidextrous charging handle and safety selector. The rifle feeds from a 5-round magazine and ships with no factory sights. Among AR-platform rifles in the AR rifles category, the Sentinel favors precision shooters who want a purpose-built 8.6 Blackout platform.
