DuraMag builds this Speed-series magazine (part no. 2023009175CPD) to run in any AR-15 pattern rifle, with a lightweight aluminum body dual-marked for .300 AAC Blackout and .223 Remington/5.56 NATO. Since both cartridges share the same case dimensions, the single magazine feeds either chambering without modification, which is a real convenience for owners who run more than one upper on the same lower. Finished in a distinctive Desert Gold anodized coating, it stands out from the sea of black GI-pattern magazines in a range bag or mag pouch. This DuraMag magazine is a straightforward, durable spare for any AR-15 magazine rotation.
