The Leupolds are great and get the job done. The issue, which may not be an issue any more is to test your scope to make sure it has either MOA or IPHY elevation adjustments. Some acquaintances who do or used to frequent this forum and make a living in the LR industry tell me that some days Leupold throws in MOA parts and another day, IPHY parts. Lately, though, Leupold is using all MOA parts.
