This was the first thread-type mounting standard that Pulsar used on their clip-ons, all the ones they used before had been of the bayonet type. Additionally, some devices that feature this mounting standard, such as Pulsar Krypton XG50 and Pulsar Proton XQ30, have a bayonet at the end of the eyepiece for monocular attachment. All the clip-ons that feature this mounting standard are front-mounted, meaning that they are mounted on the riflescope’s objective. Some adapters on the market fit directly on the bayonet, while a reducing ring (converter) is needed with others.
