The MAC 80041064 +4 Magazine Extension transforms standard magazine capacity by adding four additional rounds while maintaining reliable feeding and factory-level performance. This precision-engineered extension integrates seamlessly with compatible magazines, providing tactical professionals and competitive shooters with extended capacity without compromising reliability.

What Makes This Different

The MAC 80041064 features a robust aluminum construction with a Type III hard anodized finish that resists wear and corrosion better than standard polymer extensions. Unlike basic capacity enhancers that can cause feeding issues, this extension maintains the original spring tension geometry through its engineered follower system. The black anodized surface provides a professional appearance that matches most factory finishes while offering superior durability compared to painted alternatives.

  • CNC-machined aluminum construction with Type III hard anodizing for maximum durability
  • Precision-engineered follower maintains reliable feeding under all conditions
  • Black anodized finish matches factory magazine aesthetics

  • Lightweight design adds minimal weight while maximizing capacity
Field testing demonstrates consistent cycling through thousands of rounds across various ammunition weights and manufacturers. The extension performs reliably in competitive shooting environments where rapid magazine changes and consistent feeding are critical. Temperature extremes from -20°F to 140°F show no impact on functionality, making it suitable for duty use in diverse climates. The anodized finish resists scratching and wear from repeated magazine insertions and tactical gear contact.
