One of the new tactical flashlights available from Surefire... "Ultra high-output incandescent flashlight for tactical, duty, or searchlight use. Effectively a wider-bodied, slightly heavier, more powerful version of our M4. Produces a smooth, brilliant, pre-focused, long-range beam with over twelve times the light of a big two-D-cell flashlight—bright enough to temporarily blind and disorient a person by impairing his night-adapted vision. Light output can be doubled to a stunning 500 lumens with included MN21 lamp. Has integral shock-isolation system to withstand repeated recoil or impact.

FEATURES

• Shock-isolation system provides extra recoil/impact protection for lamp filament
