I've never seen a shooter positioned adjacent to someone shooting a braked rifle that loved the experience. Assuming your fellow shooters might appreciate being slammed with the pressure wave from your rifle is ridiculous at the very least.
I don't think we should always make this 100% assumption that every shooter goes to a public range and shoots on benches next to other shooters. I'm trying to remember.... I think I was still living in Norman the last time I belonged to a public range or fired a rifle on one. And we left Norman in 1993.
There are good arguments for brakes. And some against. But since I NEVER shoot anywhere near another shooter... that one doesn't apply.
