Frequently Asked Questions

Is this magazine truly blocked to 10 rounds, and how is it restricted?

Yes. This MFT Extreme Duty magazine is permanently blocked to a 10-round capacity to comply with California's magazine capacity restrictions. While the external body is the same full-size profile as a standard 30-round magazine, the internal follower and block prevent it from accepting more than 10 rounds. It is sold ready for use in California and other states with similar capacity limits.

What firearms is this magazine compatible with beyond the AR-15/M4?

The MFT Extreme Duty Magazine is primarily designed for AR-15 and M4-pattern rifles chambered in 5.56 NATO or .223 Rem. It is also compatible with many non-AR platforms that accept standard STANAG-pattern magazines, including certain bolt-action rifles and pistol-caliber carbines configured for AR-style mags. Always verify compatibility with your specific firearm before use.

How does the long glass fiber polymer compare to standard polymer magazines?

Long glass fiber polymer is a significant upgrade over standard polymer compounds. The glass fibers woven into the material dramatically increase tensile strength, impact resistance, and thermal stability, allowing the magazine to withstand drops, rough handling, and extreme temperatures that would crack or deform lesser materials. This is the same class of materials used in demanding military and law enforcement applications, making it an excellent choice for hard-use environments.
