The Streamlight TLR-RM 2 tactical gun mount light uses the same technology that US special operations use. The TLR-RM 2 gun mounted tactical light will not interfere with the balance of your gun. It is intensely bright, virtually indestructible, and is designed to attach/detach in less than two seconds. The one handed snap on and tighten interface keeps your hands away from the gun's muzzle when attaching/detaching the Streamlight TLR-RM 2 weapon mounted light. The Streamlight TLR-RM 2 is MIL-SPEC 810F performance tested, and is built to meet MIL-SPECs. The TLR-RM 2 tactical light attaches to Glock rails and any MIL-STD 1913 Picatinny rail. The TLR tactical light gives you ever advantage in any low light situation. The Streamlight TLR-RM 2 is perfect for law enforcement, security, military, police, and home defense.
