I can add some weight to this as well as i use this light everyday whilst on duty, while i do not use the Sniper as a weapon mounted light. The Q5 version is fantastici highly recommend it, you shouldn't have any problems lighting up targets out to 60 yards. The Sniper offers a good mix of throw and spill. I have never had a problem with mine.
Personally I choose the rechargeable cell, but that is because my light sees a lot of use. If you are using it regularly i would recommend choosing the rechargeable set up to save yourself a few dollars in the long term.
Hope this helped
