Ammunition pricing is per box. ATTENTION – California Customers
Brownells is still shipping ammunition orders to California but the process has changed to comply with California Proposition 63. We must now ship ammunition purchased online to an FFL or California-approved ammunition dealer. After placing your order, a Brownells representative will contact you to ensure your ammunition arrives quickly and in compliance with the law.
A battle rifle is only as reliable as its magazine – make sure the one in your rifle is from Brownells. When the difference between a “bang” and a “click” is life and death, a magazine failure is more than inconvenient – it can be fatal. So when we decided to build our own AR-15/M16 magazines, reliability was our first priority. Some of us have sons and daughters serving overseas or in law enforcement, and we aimed to build the kind of magazine we’d trust their lives with. We started with a clean slate, then worked out the bugs on the drawing board and the test range before we offered a single mag for sale, so you get a magazine of uncompromising quality and reliability that’s built to last and ready to run hard. When failure is not an option, these magazines deliver on the range, in the field, in a tactical situation, under fire. Load these smooth-feeding magazines to maximum capacity and fire the full 30 rounds you expect. No jams, no misfeeds, no hangups.
All components are made of mil-spec materials and are manufactured under strict, ISO quality control standards. The heat-treated, welded aluminum body is hard-anodized for superior corrosion resistance, then given a tough, dry-lube coating to eliminate the need for additional lubricants that would attract dust, sand, or dirt. The latest military-type, glass-fiber reinforced composite follower further guarantees flawless feeding in the harshest tactical conditions. Choose from a mil-spec stainless steel spring. Updated material and design features like those in our 30-round magazine have been adapted to our straight-bodied, 20-round model. All models are available in standard military Gray. Since we manufacture these mags ourselves, we can maintain a large inventory. So, if you need magazines in a hurry, even in quantity, we can get them to you ASAP.
