Hunter5325, thanks much. That helps. The weight, bulk, and mechanical performance, I'm familiar with from my very similar 5.5-22. It sounds like as long as I can stomach the physical size, the optical performance (low power, eye relief, low light, etc) will be good.
I tend to be distrustful of these 5x and 6x zoom-ratio scopes in the sense that I am skeptical that they deliver the low end. Sounds like this one DOES. Cool.
