The new SureFire Pro series lights are straight FIRE son! The adjustable mount comes with both picatiny and mlok adapters and allows the light to be mounted on either side of your rifle in 1, 3, 5, 6, 9 and 10 o’clock positions. It saves users the hassle of buying light mounts and saves weight. SureFire is smoking the competition and the new Pro Series solidifies their lead. Worth the money.
