An ASC 30-round .223 Rem/5.56 NATO ammunition storage magazine built to feed reliably through your AR platform rifle, day in and day out. Ammunition Storage Components manufactures these magazines from 6061-T6 aluminum in the USA, then hard-anodizes the finished product to military spec—the kind of durability you expect when precision and longevity matter. The mag is fully compatible with standard AR-15, M4, and M16 platforms chambered in .223 Remington or 5.56 NATO, making it a versatile addition to your loadout whether you're training at the range or in the field.
The engineering is straightforward and proven: a rigid aluminum body paired with a chrome silicon spring and mil-spec polymer follower that feeds rounds consistently without hang-ups. The aluminum floor plate comes secured and ready to use. At 30 rounds, this magazine gives you serious capacity for high-volume shooting sessions, tactical training, or hunting situations where follow-up shots matter. The flat dark earth finish blends into most tactical setups and resists wear that might show on plain aluminum.
ASC's commitment to domestic manufacturing means every step of the process—from raw stock to hard-coat anodizing per MIL-A-8625 Type III specification—happens in the USA. That's reflected in the build quality: no corner-cutting, no mystery alloys, no outsourced shortcuts. If you've run budget-brand mags that develop wobble, lose tension, or develop feeding issues, you'll notice the difference immediately in the stiffness and consistency of an ASC mag. Load it once, trust it repeatedly.

Yes. ASC 30-round magazines are designed for standard AR-platform rifles including AR-15, M4, and M16 chambered in .223 Remington or 5.56 NATO. They follow mil-spec dimensions and will function in any standard magwell.
The supplied facts confirm ASC magazines are compatible with .300 Blackout as well as .223/5.56. However, this product listing is specifically for .223 Rem/5.56 NATO. If you shoot .300 Blackout, verify compatibility with product selection or contact us.
You receive the assembled 30-round magazine with the aluminum body, follower, spring, and floor plate installed and ready to load and use.
ASC manufactures from 6061-T6 aluminum (not pot metal or lower-grade alloys) and hard-anodizes to military specification in the USA. The result is a magazine that maintains feed reliability and resists wear far longer than budget brands. The rigid construction and quality spring tension mean fewer jams and consistent performance over thousands of rounds.
