RE: bsa scopes?
My brother has a BSA scope on a Rem 7mm Mag. I have shot it and it is a good scope for the money. He has had no issues out of it so far it, according to him, has worked very well in low light conditions.
I however have Burris and Leupold scopes and one simmons 3x9-40mm. The simmons came on a package deal with a savage rifle. The simmons is still on the rifle and has performed flawlesly.
So for your money the BSA scope are ok to good. Do they compare to higher end scopes. IMO, nope. But sometimes the cheaper scope perform very well.
Try looking at the Barska line as well. I have the Barska Binoc's and they a really good.
