FN SCAR 17S 20S Magazine .308 Win 20 Rounds

Verify this magazine’s caliber (likely .308 / 7.62×51) and confirm compatibility with your rifle (AR-10 / SR-25 pattern) — it will not fit standard AR-15 / 5.56 platforms. Steel body construction offers durability but check the follower and baseplate type for your rifle’s mag-catch and feed geometry. Capacity and finish vary by variant, so order to the listing specs and obey local capacity laws. Always function-test at the range, avoid over-loading on first use, and store magazines unloaded for long-term life of the spring.
