Duramag AR-15 300 Blackout 20 Round Black Aluminum Magazine

DURAMAG Speed magazines represent a significant evolution beyond standard USGI designs. These magazines have earned trust among OEM manufacturers, Law Enforcement, and Military units worldwide since 2011, proving their reliability in demanding conditions. The 300 Blackout 20-round capacity magazine is constructed from 6061-T6 aluminum and finished with type-III hard-coat anodizing. Unlike competitors that apply surface coatings for color, DURAMAG integrates color directly into the anodizing process, making it an inherent part of the metal itself. These magazines remain safe for extended storage while loaded without flexing or swelling, unlike polymer alternatives. Manufacturing employs Progressive die tooling, Post and Hole design, and fully robotic welding to ensure consistency and reliability with every purchase. Due to the chemical process inherent in Type 3 Hard-coat anodizing, product color finish may vary between individual magazines, even within the same batch. DURAMAG’s Quality Control process maintains an acceptable range for each color hue and rejects any magazine falling outside established specifications.
