At its core is Bergara’s ultra-reliable BMR action, built to deliver repeatable sub-MOA performance from the bench or the bush. The Extreme Series polymer stock offers a solid, no-nonsense feel with textured grip panels for control when things get fast.
Its compact profile suits work in tight cover or from the driver’s side of a ute. Proven by shooters worldwide, the Sierra Extreme in .300BLK is a tough, purpose-built rifle that holds its own in rugged country and demanding conditions.
