I lied, there are more brands than that even;

Redfield, Bausch and Lomb, sightmark, BSA, Bushnell

Lots of options. If I were you I would look that way instead of going the scout scope route. If buying a used scope I wouldn't buy one that didn't have a bunch of good detailed pictures and good description of of the condition

"If you are going to go through all the trouble to put a hole in something, why not make it a big one?"
