I have one and really like it. It is mounted on a lightweight mountain rifle (Sako 85 Finnlight) and it is the perfect size for the rifle. It went through a couple rainy days last season without missing a hitch. I shot a doe using it at 100 yards @4x on a dark, dreary morning and the sight picture was excellent. I bought a second one (got a great price) and I don't even have a rifle to put it on (yet).
