Construction and Design

The magazine body is heat treated 6061 aluminum, which provides a rigid and durable structure that resists deformation under the repeated stress of loading, feeding, and handling. Heat treating the aluminum increases the hardness and strength of the 6061 alloy beyond its base material properties, producing a more durable finished magazine body. The MIL-A-8625 Type III Class I anodized finish is a military specification hard anodize process that penetrates the aluminum surface to produce a dense, corrosion-resistant, and abrasion-resistant layer. Type III hard anodizing produces a thicker and harder coating than standard Type II anodizing, providing greater resistance to wear and surface damage under sustained field use and handling. The stainless steel spring resists corrosion and maintains consistent feed tension across the full 30-round capacity. The standard anti-tilt follower guides the top round into a consistent feed position as the magazine empties and resists the tilting behavior that can cause feeding issues with standard followers. The STANAG pattern body fits any AR-15, M16, or M4 pattern magazine well that accepts standard STANAG magazines.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Verify local and state laws regarding magazine capacity before purchasing.
