I've owned about five BSA scopes and only two of them were worth having. One was a 36X Platinum 5-start that was made in Japan. I used it in benchrest and it worked great. It held zero very well, but I only used it at one distance so I never had to worry about how it tracked since I never adjusted it. The other one, and the only one I still own, is a Platinum 6-24x that's currently on my smallbore silhouette gun. It tracks pretty well, though not exactly evenly or the amount that it should. It returns to previous settings reliably, though, so it works fine for now. The other three BSA scopes I had (one Platinum, one Contender, one Catseye) were utter junk and I gave or threw them all away. I feel lucky that the Platinum that I still own has been as reliable as it has, and plan to replace it with a Sightron as soon as funds allow.
