I did a quick search about flash suppressors in California, and it looks like if you have a detachable magazine, you need a muzzle break.
If you do a bullet button configuration, since the mag doesn't detach, a flash suppressor is okay. Check out the forums at Calguns. There's a ton of information there.
Sweet! I have a flash hider on mine, but since I bought it that way I just figured it was pre-ban or something. Thanks for the info!
