Frequently Asked Questions

What are the main legal restrictions for AR pistols in California?

In California, AR pistols are classified as assault weapons, meaning they are limited to 10-round magazines and must be equipped with a maglock device. This device prevents the separation of the upper and lower receivers, which is a common feature on non-compliant firearms.

Why are short-barreled AR pistols problematic in California?

Short AR pistols, like those with a 7.5" barrel, are particularly problematic in California due to their extreme loudness, which cannot be mitigated by suppressors as they are illegal. Their compact nature also makes them harder to grip, and legal compliance adds further complexity.

What is a maglock and why is it required for AR pistols in California?

A maglock is a compliance device that secures the upper and lower receivers of an AR-style firearm together, preventing the magazine from being dropped freely. It's required in California to circumvent assault weapon bans that target firearms with detachable magazines.

Are suppressors legal for AR pistols in California?

No, suppressors are illegal to possess in California. This significantly impacts the usability of short-barreled AR pistols, as they are notoriously loud, and the inability to use a suppressor makes them even more impractical for shooting, especially in enclosed spaces.
