In California they changed the long-gun law several times. Oh about a decade ago they made a law that you needed to use a tool to remove the magazine in a rife. This became known as the “bullet button” because you needed a tool shaped like the head of a bullet to release the magazine. You could literally use a bullet to do it, so it was stupid but not that much slower than a finger release.
Then the state decided that this was too easy, so they now require fixed magazines on long guns with various features. There is widespread non-compliance. Nobody but nobody except the most angelic law abiding people took their AR-15’s to the smith to have the bullet button replaced with a fixed magazine contraption that requires disassembly of the upper and lower receivers in order to replace the magazine. AND - you have to register them.
Of course, 10 rounds maximum in a magazine.
I could be mistaken but I think the law has been stayed pending litigation.
Bullet Button,
Like the Hokie Pokie it
Just gets silly.
