Bushnell, TRS 25 has worked well on my AR and Marlin .30-30. Old Tasco Propoints that were made in Japan before operations were moved to China, are pretty tough, and you can find them on E-Bay from time to time. I had a PDP2 that went for years with no trouble at all. Finally had a friend talk me out of it for his kid's AR. Still running on that rifle.
