Streamlight PolyTac LED Flashlight

Affordable but still bright and sturdy, Streamlight Polytac LED Flashlight is designed for the broadest range of lighting applications at the best value and would be a great upgrade for your AR15.

It has a superior grip texture for a comfortable but slip-resistant feel which makes it easy to hold on especially for the wet or sweaty hand.

The light has a light aluminum body with a polymer covering on.

It has rubber emblems on the bezel and the tail cap, but the most important components are inside.

The tail cap has a spring for the negative terminal of the battery, but it is relatively small.

Surrounding the spring is rubber, fan fold gasket. The gasket is part of the suspension as it’s not meant to keep any liquid out, but it does add an extra level of firmness to stop the batteries from moving.

Using C4® LED technology within a parabolic reflector produces a concentrated beam with optimum peripheral illumination TEN-TAP® Programming, this model Streamlight is extremely bright and could light up your backyard like daylight.

It has three settings on the control including high, low and strobe which are pretty disorienting when you kick it on.
