Sauer S10507 M18 Magazine 5rd 223 Rem/5.56 NATO Black Polymer

The Sauer S10507 M18 magazine delivers reliable feeding for Sauer 100, 101, and M18 rifle platforms in 223 Remington and 5.56x45mm NATO chamberings. This factory magazine maintains consistent performance across hunting and precision shooting applications where controlled capacity matters.

What Makes This Different

Factory Sauer magazines feature precision-molded polymer construction with steel reinforcement at critical stress points. The anti-tilt follower design prevents binding during feeding cycles, while the steel spring maintains consistent tension through thousands of loading cycles. Unlike aftermarket alternatives, these magazines undergo the same quality control standards as the rifles themselves.

Key Features

• 5-round capacity compliant with hunting regulations in most jurisdictions
• Black polymer body with steel reinforcement inserts for durability
• Anti-tilt follower ensures smooth cartridge presentation
• Compatible with Sauer 100, 101, and M18 rifle models
• Chambers both 223 Remington and 5.56x45mm NATO cartridges
• Steel magazine spring rated for extended service life
• Positive magazine catch engagement prevents accidental release

Field performance remains consistent across temperature extremes from -20°F to 140°F. The polymer body resists impact damage while maintaining dimensional stability. Hunters appreciate the reduced capacity for compliance with game laws, while precision shooters value the consistent feeding geometry that supports sub-MOA accuracy potential. The magazine functions reliably with match-grade ammunition and standard hunting loads.
