Great product - Streamlight TLR-1 HL CR123A LED Rail-Mounted Tactical Flashlight

Easy to mount, easy to use, and very bright. I bought the Streamtlight TLR-1 to mount near the muzzle of my CMMG Banshee (AR style pistol with 10" barrel) knowing that it was primarily designed for a handgun. Never the less, it still looks and works great on my Banshee with the only issue being the activation switch is a bit cumbersome for the type of gun I'm using. I still give it 5 stars because the switch is designed to straddle the front of the trigger guard on a handgun where it will be easy to manipulate with your trigger finger on the right side or left thumb on the left side.
