I have no experience with Red Dot Scopes, but I do have experience with BSA optics.

To be blunt...they are not very good in comparison with even Bushnell, Tasco or Simmons. I had one of the rifle scopes, a set of their binoculars and I currently have one of their spotting scopes.

The first two items were very poor in optical quality and overall craftsmanship while the latter (which I currently have right next to me..zeroed in on some goldfinches) was at least acceptable in clarity and quality.

Maybe someone else can give you more info.
