Duramag AR-15 300 Blackout 20 Round Aluminum Magazine

DURAMAG Speed magazines represent a genuine advancement over standard USGI magazines. These field-tested magazines combine lightweight construction with exceptional durability, earning them as the preferred choice for OEM, Law Enforcement, and Military units worldwide since 2011. The magazines feature 6061-T6 aluminum bodies with type-III hard-coat anodizing. Unlike competing magazines that rely on inferior surface coatings for color, DURAMAG’s colors are integral to the anodizing process itself, becoming part of the metal. These magazines are safe for extended storage while loaded and resist the flexing or swelling characteristic of polymer alternatives. Manufacturing employs Progressive die tooling, Post and Hole design, and fully robotic welding to ensure consistency and reliability with every purchase, guaranteed. Color Disclaimer: Type III hard-coat anodizing involves a chemical process that can result in color variation between individual magazines, including those from the same production batch. Quality Control procedures maintain an acceptable range for each color hue, with any magazine outside this range rejected during final inspection.
