I have Leupold, Redfield, Nikon and Bushnell. They're all good scopes. My last two purchases were Bushnell Elite 3500 (4-12) and 4500 (4-16) and I'm pleased with both and both were reasonably priced as they are a discontinued models. They're still available and still reasonably priced. I might add that prior to those two I've had another Bushnell Elite for 23 years on one of my deer rifles. Good luck to your brother in his search. Hope he has fun.
