Frequently Asked Questions

Is this magazine permanently blocked to 10 rounds, and is it legal in California?

Yes. This ProMag magazine is permanently restricted to a 10-round capacity, making it compliant with California's magazine capacity laws that prohibit the manufacture, importation, sale, or transfer of magazines capable of holding more than 10 rounds. It is designed and sold specifically for use in California and other states with similar restrictions. Always verify current local laws, as regulations can change.

Will this magazine fit my AR-15 or other .223/5.56 rifle?

This ProMag magazine is designed to fit any mil-spec AR-15 or M16-platform firearm chambered in 5.56 NATO or .223 Remington. It uses a standard STANAG-compatible form factor and should drop in and lock up reliably with virtually any AR-15 lower receiver that accepts standard magazines. If you have a non-standard or proprietary lower, confirm compatibility with your firearm's manufacturer before purchasing.

How does the 30-round body profile affect handling if it only holds 10 rounds?

The 30-round body profile means the magazine has the same external dimensions and familiar curved shape as a standard-capacity AR-15 magazine, which many shooters find more comfortable and natural to grip during reloads. The internal components are modified to limit feeding to 10 rounds only. This design preserves the ergonomic feel shooters are accustomed to while maintaining full legal compliance.
