I have just bought a mark 4 premier leupold x32, it will only parallex down to about 15 yards. I have heard that it is possible to use a fifty foot adaptor to bring the parallex down to 8 yards for field target shooting. Has anyone used one of these, and could they advise me as to where I could get one, perhaps there is another way of doing it. Any advise or help would greatly appreciated. Thanks Peter.
