Great light - SureFire M312 Scout LED Weapon Lights

You will not find a higher quality flashlight than those made by surefire. They are expensive but they are life long purchases, they have lifetime warranty. Having one with the ability to quick detach to whatever firearm you want makes it well worth it. I find the V models that surefire makes to be a whiter more concentrated beam than the other models despite the fact that it is half the lumens, it gives off a perfect beam.
