Available with most Bushmaster rifles, the Bushmaster 30 round magazine offers unsurpassed durability at an exceptional value. Fit for all .233/5.56mm AR15 rifles, the aluminum boxes are treated with Molybdenum Disulphide (Moly) for long lasting durability, and are stamped with a full "progressive" die. This process makes Bushmaster magazines even more durable than PTFE "Teflon" that is used on other magazines.

The surface finish of all Bushmaster magazines either meets or exceeds current MIL-PRF-46010 that is required for all U.S.G.I. magazines, and they have tempered steel springs and the baseplates are stamped with the Bushmaster logo to mark their outsanding quality. All Bushmaster magazines are approved and endorsed by the National Tactical Officers Association. A high capacity magazine that fits the AR-15 and holds either 20 or 30 rounds of .223 ammo.
