There are a few restrictions on gun grips in California. A forward grip is not allowed on rifles with a detachable magazine. However, there are ways to get around this restriction.
One is to use a pistol grip that doesn’t protrude below the barrel. Another way is to use a thumbhole stock. Some foregrips can be attached to shotguns and AR-style pistols. So there are plenty of options for people who want a forward grip on their rifle.
