Griffin Armament AR-15 Magazine Features The Griffin Armament 20 round magazine is manufactured by D&H Industries a company with decades of experience as a government contractor producing USGI pattern 30 round magazines and the largest supplier of magazines to the Israeli Defense Force. That background translates into a magazine built to strict reliability standards backed by a rigorous quality control program that includes periodic reliability testing involving thousands upon thousands of rounds fired through simulated life cycles. Constructed from aluminum the magazine is finished in a gray hardcoat anodized teflon impregnated coating that resists corrosion and reduces friction during feeding. This 20 round capacity configuration chambers 5.56mm and fits the AR15 M16 and M4 family of rifles without modification. Unlike polymer magazines which can vary from one production batch to the next due to material or internal geometry changes that are not always visible to the end user the D&H style aluminum magazine holds to a consistent specification over time. This consistency matters for shooters who rely on their magazines functioning identically across every unit in their kit whether for competition training or duty use. At just 4 ounces the magazine adds minimal weight to a loadout while still offering the durability aluminum construction provides over a lighter polymer body. For AR-platform owners who want a magazine built to a proven military contract standard rather than a commercial-grade alternative this Griffin Armament 20 round magazine delivers that dependability.
