Streamlight quality/price ration is the best! highly recommend! - Streamlight ProTac Rail Mount HL-X LED Long Gun Light

My first high end light was a Surefire Scout and it is a great light, but it is twice the cost of this Streamlight, and I had to buy all the extra's that came in the box with the Streamlight. I use streamlights on every one of my weapons now, whether pistols, EDC or rifles. The ProTac is the best value out there, and the included pad and mount makes it easy to add ergonomically to any firearm.
