The Radical Firearms 10-round magazine is designed to properly fit and feed your AR pattern firearms chambered in 12.7x42mm or .458 SOCOM. Features a steel body with a four-way, anti-tilt follower and constant-curve internal geometry for reliable feeding. Inside, the 17-7PH stainless steel spring has been pre-compressed for consistent performance and long service life. Low profile ribs and new aggressive front and rear texture gives positive control of the .458 SOCOM magazine in all environments, and a paint pen dot matrix has been added to the bottom panel of the body. The flared floorplate allows for simple, tool-less disassembly, aids in handling/extraction, and provides improved drop protection. Slim profile for better compatibility with tight double and triple magazine pouches. If you have finished building your .458 AR-15 and need a way to feed it, the Radical Firearms 10 round magazine is the one for you.

Although you can use a basic metal AR-125 magazine in a 458 SOCOM, Hollow point round feed much more reliably in these.
