Accuracy International AXSR AXMC 308 Magazine 10 Round Black 28538BL
Product Description
The Accuracy International 10-Round .308 Winchester Magazine Assembly in Black (SKU: 28538BL) is an authentic OEM multi-caliber magazine engineered specifically for Accuracy International AXSR, AXMC, and ASR rifle platforms. Designed with an extended outer body profile, this magazine allows short-action cartridges—such as .308 Winchester, 7.62x51mm NATO, and 6.5 Creedmoor—to feed directly into Lapua Magnum-sized magazine wells on AXSR, AXMC, and ASR chassis without needing a separate magazine well adapter sleeve.
Precision-manufactured in the UK from heat-treated, corrosion-resistant steel with a low-friction black finish, the 28538BL magazine utilizes a staggered double-stack, center-feed geometry to ensure smooth cartridge presentation under rapid bolt cycling. It features an anti-tilt follower and a heavy-duty stainless steel spring to guarantee consistent feeding pressure through all 10 rounds.
Whether you are running short-action caliber conversions on an AXSR long-action system or streamlining your match kit by eliminating conversion inserts, the Accuracy International 28538BL magazine delivers uncompromising military-grade reliability and seamless mag-well integration.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Fits Accuracy International AXSR, AXMC, and ASR multi-caliber rifle platforms. Designed for .308 Winchester, 7.62x51mm NATO, 6.5 Creedmoor, and 6mm Creedmoor short-action cartridges. Feeds directly into magnum-length magazine wells without requiring the 27268BL magazine adapter. Not compatible with short-action AT, AX308, or AICS pattern mag wells.
- Ensure the host rifle is completely clear, magazine removed, and chamber visually and physically verified empty.
- Verify that the correct .308 Win / short-action barrel and bolt body (e.g., SKU 28459 or 28340BL) are installed on your AXSR/AXMC chassis.
- Insert the 28538BL magazine straight up into the AXSR or AXMC magazine well until the magazine catch engages with a positive, tactile click.
- Cycle the bolt slowly to test bullet feed ramp alignment and strip-feeding force from the double-stack feed lips before match or field staging.
