I saw that mag release on a youtube video. I thought at the time that it looks like a good idea but that it might drop the mag out if you accidentally bump the release while carrying on a sling.
They were designed for competition mainly for faster mag changes. If you are slinging it around then I'd say leave the OEM one on it or switch it out to one that's a little bigger.
Good point. I was thinking of swapping mine out for the Mcarbo one but I actually don't mind the stock mag release.
