Having the scope mounted low is more important to me than having scope covers that fit. If you can see daylight between the scope and barrel without the scope covers you will have no problems. You could spend money for taller mounts, but it may mess up your scope/eye alignment.

They are cheaper than scope caps, work great, come off quickly, allow you to keep the scope low where it belongs and are easily replaced if you lose one.
