Strike Industries AR-15 Magazine - .223 Rem/5.56x45mm/300 BLK Polymer Black

The Strike Industries AR-15 magazine in .223 Rem/5.56x45mm/300 BLK is a high-capacity polymer option built for shooters who want more rounds downrange before reloading. This 33-round magazine holds three extra rounds compared to standard AR-15 magazines, giving you the flexibility to run longer strings at the range or extend your time in the field without frequent mag changes. Whether you're training hard, competing, or just stacking brass, the extra capacity adds genuine convenience to your shooting day.

Strike Industries engineered this magazine with practical features that matter in real use. The AccuRamp first round feed tray design ensures smooth, reliable feeding on reload. An anti-tilt follower prevents binding under uneven pressure regardless of which side you're loading from. Textured finger grooves on both sides give you secure grip and positive control when seating the mag—especially useful when running double or triple stacks in a mag pouch. The low-profile design lets you pack more rounds into standard pouches without bulk, and tool-less disassembly makes it easy to strip the magazine for field cleaning if needed. Built from lightweight, high-strength polymer and made in the U.S.A., this magazine delivers the balance of durability and weight savings that modern AR shooters expect.

If you're already invested in AR platform rifles chambered in .223/5.56 or .300 Blackout, this is a straightforward capacity upgrade that fits your existing platform and magazine pouches. The engineering is solid, the extra rounds are genuinely useful, and you get an American-made product that won't break the bank.
