Did exactly what it should do - Area 419 CZ457 Improved Scope Rail

It fits my rifle well and looks good. I like having the bubble on the back of the rail it helped leveling my scope but I haven't used it since, but I do like having the option to check it against the bubble on my scope ring if I need to. I like that it's open on both sides of the chamber so I can see what's going on in there when I need to. My only complaint is that sometimes a casing will bounce off the rail and not make it out of the rifle, but I'm not sure if that is the rifle or the rail. It mounts very solid and if I bought another 457 I would be purchasing another one of these rails.
