Frequently Asked Questions
Why does this magazine have a 42-round body but only hold 10 rounds?
This magazine is specifically designed for states like California that restrict magazine capacity to 10 rounds. The full-size 42-round body is permanently blocked to hold only 10 rounds, which means it retains the standard AR-15 magazine profile — including the familiar grip surface, length, and balance — while remaining legally compliant with capacity restrictions.
Will this magazine fit my AR-15 rifle?
Yes. This ProMag magazine is designed to fit standard AR-15 and M16-pattern rifles with a STANAG-compatible magazine well. It is chambered for 5.56 NATO and .223 Remington, which are interchangeable in most AR-15 platforms. If your rifle accepts standard AR-15 magazines, this one should drop in and function without modification.
Is this magazine legal to purchase in California?
Yes. This magazine is specifically manufactured and blocked to a 10-round capacity, making it compliant with California's magazine capacity laws. It falls into the "CA Blocked" category and is legal to purchase and possess in California. Always verify current local regulations, as laws can change, but this product is designed to meet the 10-round limit required by California law.
