The controlled-round-feed action with an external claw extractor and a jeweled bolt body delivers the classic Model 70 handling and function. It uses an internal box magazine with a stainless hinged floorplate and offers a 3+1 capacity. The pear-shaped, checkered bolt knob provides a secure grasp.
The 24-inch stainless barrel is fitted with Winchester’s BOSS system, combining a harmonic tuner and a ported muzzle brake. The BOSS unit includes a knurled lock ring to set and retain adjustments. The sporter-profile barrel and matte stainless finish complement the rifle’s practical, weather-resistant build.
The black synthetic stock features molded checkering and sling swivel studs, with a 13.6-inch length of pull. The receiver is drilled and tapped for scope bases, and this example wears two-piece bases and rings with a Simmons 3-10x40 scope already mounted. There are no iron sights.
Rollmarks identify it as a Classic Stainless BOSS, with New Haven manufacture and the BOSS patent reference. This configuration pairs durable stainless construction with the tunable recoil and accuracy benefits of the BOSS system in a powerful .300 Weatherby Magnum chambering.
