The Savage Arms 55189 is a detachable 5-round magazine purpose-built for .300 Winchester Magnum in the Savage 110 and 111 rifle platform. If you're running a modern Savage long-action rifle and need a reliable factory magazine that feeds consistently through competition or field use, this matte black metal magazine is engineered to handle the job. Built to AICS pattern specifications, it's designed around the extended cartridge overall length (COAL) requirements of magnum rounds, supporting loads up to 3.85 inches without compromise.
Magazine reliability is non-negotiable when precision and clean feeding matter. This Savage detachable magazine features robust black metal construction with a corrosion-resistant finish, so it won't rust out in your truck bed or weathered gear bag. The internal geometry is optimized for consistent stacking and smooth cycling of long-action cartridges, meaning you'll get repeatable performance from round one through round five without the feeding hiccups that can ruin a hunt or cost you a match stage.
Compatibility is straightforward: this magazine fits Savage 110 and 111 rifles chambered in .300 Win Mag and works with AICS-pattern chassis systems. If you're building a precision rifle setup or simply need a spare mag for your bolt gun, this is OEM Savage hardware—no guessing, no adapters required. Keep one in your range bag and one loaded and ready.
