The RemArms Model 783 Detachable Magazine is purpose-built for long-action magnum chamberings such as 7mm Remington Magnum, .300 Winchester Magnum, and .338 Magnum. Designed around the factory Model 783 bottom metal, this steel magazine offers dependable feeding and a flush fit that keeps the rifle easy to carry in the field.

This magazine is ideal as a primary replacement or a dedicated spare for range work and hunting trips where reliable follow-up shots matter. Its steel construction and carefully formed feed lips support smooth, consistent cycling with powerful magnum cartridges, while the detachable design makes loading and unloading straightforward at the bench or in camp. Backed by RemArms’ long history of building practical, hard‑use hunting rifles, this magazine complements the Model 783 platform with factory-matched performance.
