yup, have a cats eye scope, it was alright, glass was good, clear at decent range. My main problem with it was the lack of range in the elevation and windage adjustment for adjustment at long range, other then that it was a great scope.
I also know several old timers out at my local range that swear by BSA, that's all they use on their rifles. I recently switched to a leupold scope, cost about 7x as much as my BSA.... I would say it's different, and good as well, it had all the features I wanted plus it's adjustment knobs are a lot nicer.
When the heat is coming off the barrel my BSA scope would look cross eyed, with the new scope it turns funny colors and goes a little fuzzy but I can still make out the target pretty clear. Other then that I don't notice that much of a difference.
They may be cheap, but it'll work... then again I don't beat up my scopes that much, so I can't tell you how well they stand up to abuse.
Leupold is good, I can tell the quality difference, but I'm not so sure it was worth 7x as much.
Then again I've only had it for a month, maybe I'll change my mind over time.
