When you spend $456 for a simple adapter it should work. If there are additional bushings required for specific applications, they should be provided. Bought the adapter (and rubber bushing and barrel) to attach to Leupold spotting scope, waited over a month to receive it only to find that it would require additional bushings for this very common application.
Pros: Heavy Duty
Cons: Didn't work
