Streamlight TLR-2 Laser Sight Tactical Flashlight is a powerful, intensely bright, long-running, aluminum-bodied gunmount light. This Streamlight flashlight sets a whole new standard for durability. This weapon light offers the same great features as its TLR-1 sibling, but with an integrated laser sight for faster and more accurate aiming. The Streamlight TLR-2 Tactical Light w/ Laser Sight is shockproof, dustproof, and virtually indestructible; the flashlight won’t break or burn out. Streamlight has built the TLR-2 to be powered by two 3-volt CR123A lithium batteries with a 10-year storage life, providing the tactical light with at least 2.5 hours of continuous run time when in dual mode with the high power visible laser. The rail grip clamp system securely attaches/detaches quickly & easily with no tools and without putting your hands in front of the muzzle, and fits most handguns with rails as well as long guns with 1913 (Picatinny-style) rails. The Stream Light TLR2 Laser-Equipped Tactical Weapon Light gives you the advantage in any low-light situation.
