Accuracy International AXSR AXMC 300 Win Magazine 10 Round Black 26091BL
Product Description
The Accuracy International 10-Round .300 Winchester Magnum Magazine in Black (SKU: 26091BL) is an authentic OEM factory steel magazine engineered specifically for Accuracy International AXSR, AXMC, and ASR multi-caliber rifle platforms. Designed to feed standard long-action magnum cartridges—.300 Winchester Magnum and .300 PRC—this magazine provides 10-round capacity and match-grade feed reliability in harsh competition and tactical field environments.
Precision-manufactured in the UK from military-grade steel with a specialized low-friction, anti-corrosive coating, the 26091BL utilizes a staggered double-stack, center-feed geometry to ensure smooth cartridge presentation under rapid bolt cycling. It features an internal magazine length of 3.840 inches (3.910" external), allowing handloaders to load long high-BC match projectiles out to extended overall lengths.
Equipped with a removable steel floorplate, high-tensile mainspring, and anti-tilt follower, the spring and follower assembly can be quickly disassembled for routine field cleaning. Designed for direct drop-in fitment into AXSR, AXMC, and ASR chassis magwells, the 26091BL provides seamless lockup and reliable feed geometry for factory ammunition and custom handloads.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Fits Accuracy International AXSR, AXMC, and ASR multi-caliber rifles. Optimized for .300 Winchester Magnum and .300 PRC cartridges (.532" bolt face family). Feeds directly into AXSR and AXMC chassis magwells. Not compatible with short-action AT/AX308 platforms, AICS chassis, or .338 Lapua Magnum CIP magwells without appropriate bolt/barrel configurations.
- Ensure the host rifle is completely clear, magazine removed, and chamber visually and physically verified empty.
- Verify that the correct .300 Win Mag / .300 PRC barrel tenon and .300 WM bolt body (e.g., SKU 28473) are installed on your AXSR/AXMC chassis.
- Insert the 26091BL magazine straight into the AXSR or AXMC magazine well until the catch locks with an audible click.
- Cycle dummy rounds to verify smooth feed ramp transition and strip-feeding force from the double-stack feed lips before staging.
