BSA scopes are on my varmint rigs and they have NEVER showed one glint of problem in 20+ yrs. They have been in rain/sleet/mud/dropped and still keep on ticking away. I have 1 6-24 paltnum target scope and 2 of the 6-24 x44 side 30mm focus scopes. Those who say they are junk have no idea or have had a low end BSA which are not that good I will say.
