Accurate-Mag AICS .300 Win Mag Magazine — 5-Round Long Action
The Accurate-Mag AICS magazine is an OEM-grade detachable box magazine built for long-action magnum calibers. Used as factory equipment by major rifle manufacturers including Colt, Savage, Ruger, and Remington, Accurate-Mag magazines are the industry standard for AICS-pattern feeding systems. This 5-round single-stack single-feed design delivers reliable chambering in demanding conditions.
Premium Construction
Machined from steel, heat-treated for durability, and finished with a Teflon coating for smooth insertion and corrosion resistance. The single-stack single-feed (SSSF) design ensures consistent cartridge presentation to the bolt face, eliminating the double-feed issues that can occur with staggered-stack designs in magnum cartridges.
Universal AICS Fit
Fits all rifles with AICS-pattern magazine wells, including Bergara B14 HMR, Bergara B14 Wild HMR, Remington 700 in AICS chassis, Savage with AICS bottom metal, and other platforms using the Accuracy International magazine standard.
