MAC 80041064 +4 Magazine Extension - 2-Round Capacity Increase

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.

Field testing demonstrates consistent cycling through thousands of rounds across various ammunition weights and manufacturers.
