Frequently Asked Questions
Is this magazine truly California-legal for capacity-restricted states?
Yes. This magazine is permanently blocked to a 10-round capacity, making it compliant with California's magazine capacity restrictions as well as other states that limit detachable magazines to 10 rounds. The block is factory-installed in a 30-round body, so the overall form factor mirrors a standard magazine while remaining within legal limits. Always verify current regulations in your jurisdiction before purchasing.
Will this magazine work in my HK SP5K or a cloned MP5 pistol?
This magazine is designed to fit the MAC 5, MAC 5K, MP5, MP5K, and SP5K platforms. It should function correctly in genuine HK SP5K pistols and most MP5-pattern clones that accept standard MP5-spec steel magazines. If you own a clone or third-party MP5-style firearm, we recommend confirming magazine compatibility with your specific model before purchase.
What is the difference between this mag and a standard 30-round MP5 magazine?
Externally and dimensionally, this magazine is nearly identical to a standard 30-round MP5 steel magazine — it shares the same body, profile, and form factor. The key difference is an internal block that physically limits the usable capacity to 10 rounds. This means you get the same handling, fit, and feel of a full-size magazine while staying compliant with state law.
