It's a nice light. It's definately bright enough, almost too bright in fact. It'll mount on your scope, and stay put pretty good.
I've come full circle on my night hunting as far as lights go. I started out years ago with a handheld. I switched to gun mounted lights for a while, and I've been back to using only handhelds now for a long time.
I hunt alone almost all the time. I have to do all the sweeping with the light myself, and it's very aggravating trying to spot with a hand held, then switch to the gun light for a shot. You could use the gun light for spotting, but it's not only un-safe(might point it in a bad direction), but it'd keep you swinging your gun around while you should be trying to sit still.
I practice shooting at night quite a bit. If you'll practice holding the light, and gun together, you'll get where it's second nature.
