I have used BSA before and I can say that some are good and some are not. Make sure it is waterproof, shockproof, and fogproof. I have had some issues with them not doing well with the shock and fogging; that said I have had the same problems with leupold's as well, sometimes you get a lemon. I would ask which bushnell scope are you looking at, as BSA isn't the worst scope on the market but I wouldn't say that they are as good as some of the bushnell stuff either. But to answer that I would spend the extra money on your scope as it is every bit as important as the rifle you're shooting.
