Whats the difference between pinned and blocked mags?

Confused...

Here's where I was looking when I came across them.

My guess is the pinned mags have a rivet (or other such device) going through the mag body preventing the follower from moving down far enough to accept over 10 rds.

Blocked mags have a big block inside them preventing the follower from moving down far enough to accept over 10 rds.

Yup, and in my experience, blocked mags are nor permanently blocked and can be disassembled

This. I have 20 round PMAGS blocked to 10 for my AR, all I have to do is swap out the block and I am good to go when I am in Arizona. If only swapping out my bullet button was that painless...
