Both are good. I prefer the Talley myself. I’ve always been a big fan of their scope rails. I use the Short Action, 20MOA rail and love it. Great look. Great fit. Exceptionally high quality. And Talley gives great customer service.

Honestly, the bubble level rails are a gimmick!! Think about it… when you are on scope, the bubble level in the rail is far too low to see. You would need to come off scope & move your head/eyesight down to see it correctly. Which completely makes the point of having it moot! Where as the scope tube mount bubble level is right there at eye level, easily seen from the corner of one’s vision without ever coming off scope or target.

Watch out for gimmicks! Something might seem like a good idea until you put it into practice. Trick is to really think about its use BEFORE wasting money on a gimmicky product.
