Winchester built its reputation in the 1860s with the legendary repeating lever-action rifles and later cemented its legacy in 1936 with the introduction of the iconic Model 70 bolt-action sporting rifle. Both designs remain in production today, a testament to Winchester’s enduring quality and innovation. Carrying that same tradition into the world of airguns, the Winchester Model 45/55 and 45/55RS spring-piston rifles draw direct inspiration from the Model 70. The Model 55RS and 45RS are designed as scope-only air rifles, equipped with an integral moderator and scope rail, while the Model 55 and 45 feature fiber-optic open sights for classic precision. For added versatility, the Model 55 can also be fitted with a scope on its top rail. Though the variants differ slightly in configuration, both rifles share the same durable build quality and market-leading features that make them stand out in their class.
