Duramag AR-15 300 Blackout 20 Round Aluminum Magazine

DURAMAG Speed magazines represent a significant evolution beyond standard USGI designs. Since 2011, these battle-tested magazines have been the trusted choice of OEM manufacturers, Law Enforcement, and Military units worldwide. Built from 6061-T6 aluminum with Type-III hard-coat anodizing, they deliver lightweight performance without sacrificing durability. DURAMAG’s color options are integral to the anodizing process itself—not applied as a surface coating—ensuring lasting finish quality. These magazines remain safe when stored fully loaded and resist the flexing and swelling issues common to polymer alternatives. Manufactured using Progressive die tooling, Post and Hole design, and fully robotic welding, every magazine meets exacting consistency standards with each purchase. Note: Type 3 Hard-coat anodizing involves chemical processes that can produce color variations between magazines, even within the same production batch. DURAMAG’s Quality Control maintains an acceptable range for each color and rejects magazines falling outside specifications.
