Will chew up your rail.
Works OK. Make sure you loctite the set screws of they will back out. The screws will dig into your rail. Be aware of it if you are worried about it. None of my rifles are safe queens, but I am not real hot on a cheap part that damages a $200+ rail system. This worked to test s setup. Into the parts bin it will go. A higher quality part has replaced it.
