Maven's website says these are genuine Outdoorsmans studs, made of "machined aluminum".
Really cleanly machined aluminum can look like plastic. Tap it on a tooth to easily tell the difference.
Just a question I have. Swarovski has authorized Outdoorsmans to install their stud on the binoculars, and Swaro will still honor the warranty. What about the installation of the Maven (Kramer) stud? Might want to check with Swaro to see if they will honor the warranty if there is a problem after the installation of the Kramer stud.
